AN977 APPLICATION NOTE GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124/F150/F250 (0.35 µm) by Microcontroller Division Applications INTRODUCTION Microcontrollers for embedded applications tend to integrate more and more peripherals as well as larger memories. Providing the right products with the right features such as Flash, emulated EEPROM and a wide range of peripherals at the right cost is always a challenge. That is why it is mandatory to shrink the microcontroller die size regularly as soon as the technology will allow it. This major step applies to the ST92F120. The purpose of this document is to present the differences between the ST92F120 microcontroller in 0.50 micron technology versus the ST92F124/F150/F250 in 0.35 micron technology. It provides some guidelines for upgrading applications for both its software and hardware aspects. In the first part of this document, the differences between the ST92F120 and ST92F124/F150/ F250 devices are listed. In the second part, the modifications required for the application hardware and software are described. AN977/0203 1/17 1 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124... 1 UPGRADING FROM THE ST92F120 TO THE ST92F124/F150/F250 ST92F124/F150/F250 microcontrollers using 0.35 micron technology are similar to ST92F120 microcontrollers using 0.50 micron technology, but shrinking is used to add some new features and to improve the performances of ST92F124/F150/F250 devices. Almost all peripherals keep the same features, which is why this document focuses only on the modified sections. If there is no difference between the 0.50 micron peripheral compared to the 0.35 one, other than its technology and design methodology, the peripheral is not presented. The new analog to digital converter (ADC) is the major change. This ADC uses a single 16 channel A/ D converter with 10 bits resolution instead of two 8-channel A/D converters with 8-bit resolution. The new memory organization, new reset and clock control unit, internal voltage regulators and new I/O buffers will almost be transparent changes for the application. The new peripherals are the Controller Area Network (CAN) and the asynchronous Serial Communication Interface (SCI-A). 1.1 PINOUT The ST92F124/F150/F250 was designed in order to be able to replace the ST92F120. Thus, pinouts are nearly the same. The few differences are described below: – Clock2 was remapped from port P9.6 to P4.1 – Analog input channels were remapped according to the table below. Table 1. Analog Input Channel Mapping PIN P8.7 ... P8.0 P7.7 ... P7.0 ST92F120 Pinout A1IN0 ... A1IN7 A0IN7 ... A0IN0 ST92F124/F150/F250 Pinout AIN7 ... AIN0 AIN15 ... AIN8 – RXCLK1(P9.3), TXCLK1/ CLKOUT1 (P9.2), DCD1 (P9.3), RTS1 (P9.5) were removed because SCI1 was replaced by SCI-A. – A21(P9.7) down to A16 (P9.2) were added in order to be able to address up to 22 bits externally. – 2 new CAN peripheral devices are available: TX0 and RX0 (CAN0) on ports P5.0 and P5.1 and TX1 and RX1 (CAN1) on dedicated pins. 1.2 RW RESET STATE Under Reset state, RW is held high with an internal weak pull-up whereas it was not on the ST92F120. 2/17 2 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124... 1.3 SCHMITT TRIGGERS – I/O ports with Special Schmitt Triggers are no longer present on the ST92F124/F150/F250 but are replaced by I/O ports with High Hysteresis Schmitt Triggers. The related I/O pins are: P6[5-4]. – Differences on the VIL and VIH. See Table 2. Table 2.

They are only reported for design guide lines not tested in production. 1.4 MEMORY ORGANIZATION 1.4.1 External memory On the ST92F120, only 16 bits were externally available. Now, on the ST92F124/F150/F250 device, the 22 bits of the MMU are externally available. This organization is used to make it 3/17 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124... easier to address up to 4 external Mbytes. But segments 0h to 3h and 20h to 23h are not externally available. 1.4.2 Flash Sector Organization Sectors F0 to F3 have a new organization in the 128K and 60K Flash devices as shown in Table 5 and Table 6. Table 3. and Table 4 show the previous organization. Table 3.

This way, only one DPR is used to point to both the E 3PROM variables and Flash & E2PROM control registers. But the registers are still accessible at the previous address. The new register addresses are: – FCR 0x221000 & 0x224000 – ECR 0x221001 & 0x224001 – FESR0 0x221002 & 0x224002 – FESR1 0x221003 & 0x224003 In the application, these register locations are usually defined in the linker script file. 5/17 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124... 1.5 RESET AND CLOCK CONTROL UNIT (RCCU) 1.5.1 Oscillator A new low power oscillator is implemented with the following target specifications: – Max. 200 µamp. consumption in Running mode, – 0 amp. in Halt mode, Figure 1. ST92F120 Internal Oscillator Figure 2. ST92F124/F150/F250 Internal Oscillator VDD HALT ILOAD REF CLOCK1 OSCOUT RPOL OSCIN CLOCK INPUT BUFFER OSCIN VR02086A OSCOUT 1.5.2 PLL One bit (bit7 FREEN) has been added to the PLLCONF register (R246, page 55), this is to enable Free Running mode. The reset value for this register is 0x07. When the FREEN bit is reset, it has the same behaviour as in the ST92F120, meaning that the PLL is turned off when: – entering stop mode, – DX(2:0) = 111 in the PLLCONF register, – entering low power modes (Wait For Interrupt or Low Power Wait for Interrupt) following the WFI instruction. When the FREEN bit is set and any of the conditions listed above occur, the PLL enters Free Running mode, and oscillates at a low frequency which is typically about 50 kHz. In addition, when the PLL provides the internal clock, if the clock signal disappears (for instance due to a broken or disconnected resonator...), a safety clock signal is automatically provided, allowing the ST9 to perform some rescue operations. The frequency of this clock signal depends on the DX[0..2] bits of the PLLCONF register (R246, page55). Refer to the ST92F124/F150/F250 datasheet for more details. 6/17 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124... 1.6 INTERNAL VOLTAGE REGULATOR In the ST92F124/F150/F250, the core operates at 3.3V, while the I/Os still operate at 5V. In order to supply the 3.3V power to the core, an internal regulator has been added. Actually, this voltage regulator consists of 2 regulators: – a main voltage regulator (VR), – a low power voltage regulator (LPVR). The main voltage regulator (VR) supplies the current required by the device in all operating modes. The voltage regulator (VR) is stabilized by adding an external capacitor (300 nF minimum) on one of the two Vreg pins. These Vreg pins are not able to drive other external devices, and are only used for regulating the internal core power supply. The low power voltage regulator (LPVR) generates a non-stabilized voltage of approximately VDD/2, with minimum internal static dissipation. The output current is limited, so it is not sufficient for full device operation mode. It provides reduced power consumption when the chip is in Low Power mode (Wait For Interrupt, Low Power Wait For Interrupt, Stop or Halt modes). When the VR is active, the LPVR is automatically deactivated. 1.7 EXTENDED FUNCTION TIMER The hardware modifications in the Extended Function Timer of the ST92F124/F150/F250 as compared to the ST92F120 only concern the interrupt generation functions. But some specific information has been added to the documentation concerning Forced Compare mode and One Pulse mode. This information may be found in the updated ST92F124/F150/F250 Datasheet. 1.7.1 Input Capture/Output Compare On the ST92F124/F150/F250, the IC1 and IC2 (OC1 and OC2) interrupts can be enabled separately. This is done using 4 new bits in the CR3 register: – IC1IE=CR3[7]: Input Capture 1 Interrupt Enable. If reset, Input Capture 1 interrupt is inhibited. When set, an interrupt is generated if the ICF1 flag is set. – OC1IE=CR3[6]: Output Compare 1 Interrupt Enable. When reset, Output Compare 1 interrupt is inhibited. When set, an interrupt is generated if the OCF2 flag is set. – IC2IE=CR3[5]: Input Capture 2 Interrupt Enable. When reset, Input Capture 2 interrupt is inhibited. When set, an interrupt is generated if the ICF2 flag is set. – OC2IE=CR3[4]: Output Compare 2 Interrupt Enable. When reset, Output Compare 2 Interrupt is inhibited. When set, an interrupt is generated if the OCF2 flag is set. Note: The IC1IE and IC2IE (OC1IE and OC2IE) interrupts are not significant if the ICIE (OCIE) is set. In order to be taken into account, the ICIE (OCIE) must be reset. 7/17 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124... 1.7.2 PWM Mode The OCF1 bit cannot be set by hardware in PWM mode, but the OCF2 bit is set every time the counter matches the value in the OC2R register. This can generate an interrupt if the OCIE is set or if the OCIE is reset and OC2IE is set. This interrupt will help any application where pulse widths or periods need to be changed interactively. 1.8 A/D CONVERTER (ADC) A new A/D converter with the following main features has been added: – 16 channels, – 10-bit resolution, – 4 MHz maximum frequency (ADC clock), – 8 ADC clock cycles for sampling time, – 20 ADC clock cycle for conversion time, – Zero input reading 0x0000, – Full scale reading 0xFFC0, – Absolute accuracy is ± 4 LSBs. This new A/D converter has the same architecture as the previous one. It still supports the analog watchdog feature, but now it uses only 2 of the 16 channels. These 2 channels are contiguous and channel addresses can be selected by software. With the previous solution using two ADC cells, four analog watchdog channels were available but at fixed channel addresses, channels 6 and 7. Refer to the updated ST92F124/F150/F250 Datasheet for the description of the new A/D Converter. 1.9 I²C 1.10 I²C IERRP BIT RESET On the ST92F124/F150/F250 I²C, the IERRP (I2CISR) bit can be reset by software even if one of the following flags is set: – SCLF, ADDTX, AF, STOPF, ARLO and BERR in the I2CSR2 register – SB bit in the I2CSR1 Register It is not true for the ST92F120 I²C: the IERRP bit cannot be reset by software if one these flags is set. For this reason, on the ST92F120, the corresponding interrupt routine (entered following a first event) is re-entered immediately if another event occurred during the first routine execution. 8/17 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124... 1.10.1 START EVENT REQUEST A difference between the ST92F120 and the ST92F124/F150/F250 I²C exists on the START bit generation mechanism. To generate a START event, the application code sets the START and ACK bits in the I2CCR register: – I2CCCR |= I2Cm_START + I2Cm_ACK; Without the compiler optimization option selected, it is translated in assembler the following way: – or R240,#12 – ld r0,R240 – ld R240,r0 The OR instruction sets the Start bit. On the ST92F124/F150/F250, the second load instruction execution results in a second START event request. This second START event occurs after the next byte transmission. With any of the compiler optimization options selected, the assembler code does not request a second START event: – or R240,#12 1.11 NEW PERIPHERALS – Up to 2 CAN (Controller Area Network) cells have been added. Specifications are available in the updated ST92F124/F150/F250 Datasheet. – Up to 2 SCIs are available: the SCI-M (Multi-protocol SCI) is the same as on the ST92F120, but the SCI-A (Asynchronous SCI) is new. The specifications for this new peripheral are available in the updated ST92F124/F150/F250 Datasheet. 9/17 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124... 2 HARDWARE & SOFTWARE MODIFICATIONS TO THE APPLICATION BOARD 2.1 PINOUT – Due to its remapping, CLOCK2 can not be used in the same application. – SCI1 can only be used in asynchronous mode (SCI-A). – The modifications of the analog input channels mapping can be easily handled by software. 2.2 INTERNAL VOLTAGE REGULATOR Due to the presence of the internal voltage regulator, external capacitors are required on the Vreg pins in order to provide the core with a stabilized power supply. In the ST92F124/F150/ F250, the core operates at 3.3V, while the I/Os still operate at 5V. The minimum recommended value is 600 nF or 2*300 nF and the distance between the Vreg pins and the capacitors must be kept to a minimum. No other modifications need to be made to the hardware application board. 2.3 FLASH & EEPROM CONTROL REGISTERS AND MEMORY ORGANIZATION To save 1 DPR, the symbol address definitions that correspond to the Flash and EEPROM control registers can be modified. This is generally done in the linker script file. The 4 registers, FCR, ECR, and FESR[0:1], have been defined at 0x221000, 0x221001, 0x221002 and 0x221003, respectively. The 128-Kbyte Flash sector reorganization also affects the linker script file. It must be modified in compliance with the new sector organization. Refer to Section 1.4.2 for the description of the new Flash sector organization. 2.4 RESET AND CLOCK CONTROL UNIT 2.4.1 Oscillator 2.4.1.1 Crystal Oscillator Even if the compatibility with the ST92F120 board design is maintained, it is no longer recommended to insert a 1MOhm resistor in parallel with the external crystal oscillator on a ST92F124/F150/F250 application board. 10/17 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124...

It is recommended to surround the crystal oscillator by a ground ring on the printed circuit board and to apply a coating film to avoid humidity problems, if necessary. 2.4.1.3 External clock Even if compatibility with the ST92F120 board design is maintained, it is recommended to apply the external clock on the OSCOUT input. The advantages are: – a standard TTL input signal can be used whereas the ST92F120 Vil on the external clock is between 400mV and 500mV. – the external resistor between OSCOUT and VDD is not required.

To use free running mode in the conditions described in Section 1.5, the PLLCONF[7] bit must be set. 2.4.2.2 Safety Clock Mode Using the ST92F120, if the clock signal disappears, the ST9 core and peripheral clock is stopped, nothing can be done to configure the application in a safe state. The ST92F124/F150/F250 design introduces the safety clock signal, the application can be configured in a safe state. When the clock signal disappears (for instance due to a broken or disconnected resonator), the PLL unlock event occurs. The safer way to manage this event is to enable the INTD0 external interrupt and to assign it to the RCCU by setting the INT_SEL bit in the CLKCTL register. The associated interrupt routine checks the interrupt source (refer to the 7.3.6 Interrupt Generation Chapter of the ST92F124/F150/F250 datasheet), and configures the application in a safe state. Note: The peripheral clock is not stopped and any external signal generated by the microcontroller (for instance PWM, serial communication...) must be stopped during the first instructions executed by the interrupt routine. 2.5 EXTENDED FUNCTION TIMER 2.5.1 Input Capture / Output Compare In order to generate a Timer Interrupt, a program developed for the ST92F120 may need to be updated in certain cases: – If Timer Interrupts IC1 and IC2 (OC1 and OC2) are both used, ICIE (OCIE) of register CR1 has to be set. The value of the IC1IE and IC2IE (OC1IE and OC2IE) in the CR3 register is not significant. So, the program does not have to be modified in this case. – If only one Interrupt is needed, ICIE (OCIE) must be reset and IC1IE or IC2IE (OC1IE or OC2IE) must be set depending on the interrupt used. – If none of the Timer Interrupts are used, ICIE, IC1IE and IC2IE (OCIE, OC1IE and OC2IE) they must all be reset. 12/17 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124... 2.5.2 PWM Mode A Timer Interrupt can now be generated each time Counter = OC2R: – To enable it, set OCIE or OC2IE, – To disable it, reset OCIE AND OC2IE. 2.6 10-BIT ADC Since the new ADC is entirely different, the program will have to be updated: – All data registers are 10 bits, which includes the threshold registers. So each register is divided into two 8-bit registers: an upper register and a lower register, in which only the 2 most significant bits are used: Table 7. DiHR 7 Di.9 0 Di.8 Di.7 Di.6 Di.5 Di.4 Di.3 Di.2 Table 8. DiLR 7 Di.1 0 Di.0 0 0 0 0 0 0 – The start conversion channel is now defined by bits CLR1[7:4] (Pg63, R252). – The analog watchdog channels are selected by bits CLR1[3:0]. The only condition is that the two channels must be contiguous. – The ADC clock is selected with CLR2[7:5] (Pg63, R253). – Interrupt registers have not been modified. Because of the increased length of ADC registers, the register map is different. The location of the new registers is given in the description of the ADC in the updated ST92F124/F150/F250 Datasheet. 2.7 I²C 2.7.1 IERRP BIT RESET In the ST92F124/F150/F250 interrupt routine dedicated to the Error Pending event (IERRP is set), a software loop must be implemented. This loop checks every flag and executes the corresponding needed actions. The loop will not end until all flags are reset. At the end of this software loop execution, the IERRP bit is reset by software and the code exits from the interrupt routine. 13/17 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124... 2.7.2 START Event Request To avoid any unwanted double START event, use any of the compiler otpimization options, in the Makefile. For instance: CFLAGS = -m$(MODEL) -I$(INCDIR) -O3 -c -g -Wa,-alhd=$*.lis 14/17 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124... 3 UPGRADING AND RECONFIGURING YOUR ST9 HDS2V2 EMULATOR 3.1 INTRODUCTION This section contains information about how to upgrade your emulator’s firmware or reconfigure it to support a ST92F150 probe. Once you have reconfigured your emulator to support a ST92F150 probe you can configure it back to support an other probe (for example a ST92F120 probe) following the same procedure and choosing the suitable probe. 3.2 PREREQUISITES TO UPGRADING AND/OR RECONFIGURING YOUR EMULATOR The following ST9 HDS2V2 emulators and emulation probes support upgrades and/or reconfiguration with new probe hardware: – ST92F150-EMU2 – ST92F120-EMU2 – ST90158-EMU2 and ST90158-EMU2B – ST92141-EMU2 – ST92163-EMU2 Before trying to perform the upgrade/reconfiguration of your emulator, you must ensure that ALL of the following conditions are met: – The monitor version of your ST9-HDS2V2 emulator is higher than or equal to 2.00. [You can see which monitor version your emulator has in the Target field of the About ST9+ Visual Debug window, which you open by selecting Help>About.. from the ST9+ Visual Debug’s main menu.] – If your PC is running on the Windows ® NT ® operating system, you must have the administrator privileges. – You must have installed the ST9+ V6.1.1 (or later) Toolchain on the host PC connected to your ST9 HDS2V2 emulator. 15/17 GUIDELINES FOR UPGRADING FROM THE ST92F120 (0.50 µm) TO THE ST92F124... 3.3 HOW TO UPGRADE/RECONFIGURE YOUR ST9 HDS2V2 EMULATOR The procedure tells you how to upgrade/reconfigure your ST9 HDS2V2 emulator. Be sure you meet all the prerequisites before starting, otherwise you could damage your emulator by performing this procedure. 1.
