PIC16(L)F1938/1939 Silicon Errata Issues Note: Work around This document summarizes all silicon errata issues from all revisions of silicon, previous as well as current. Only the issues indicated by the shaded column in the following tables apply to the current silicon revision (A3). 1. Module: ADC 1.1 Analog-to-Digital Conversion An ADC conversion may not complete under these conditions: 1. 2. When FOSC is greater than 8 MHz and it is the clock source used for the ADC converter. The ADC is operating from its dedicated internal FRC oscillator and the device is not in Sleep mode (any FOSC frequency). When this occurs, the ADC Interrupt Flag (ADIF) does not get set, the GO/DONE bit does not get cleared, and the conversion result does not get loaded into the ADRESH and ADRESL result registers. FIGURE 1: Method 1: Select the system clock, FOSC, as the ADC clock source and reduce the FOSC frequency to 8 MHz or less when performing ADC conversions. Method 2: Select the dedicated FRC oscillator as the ADC conversion clock source and perform all conversions with the device in Sleep. Method 3: This method is provided if the application cannot use Sleep mode and requires continuous operation at frequencies above 8 MHz. This method requires early termination of an ADC conversion. Provide a fixed time delay in software to stop the A-to-D conversion manually, after all 10 bits are converted, but before the conversion would complete automatically. The conversion is stopped by clearing the GO/ DONE bit in software. The GO/ DONE bit must be cleared during the last ½ TAD cycle, before the conversion would have completed automatically. Refer to Figure 1 for details. INSTRUCTION CYCLE DELAY CALCULATION EXAMPLE FOSC = 32 MHz TCY = 4/32 MHz = 125 nsec TAD = 1 µsec, ADCS = FOSC/32 88 TCY 84 TCY 8 TCY } 4 TCY 11 TAD Stop the A/D conversion between 10.5 and 11 TAD cycles. See the Analog-to-Digital Conversion Timing diagram in the Analog-to-Digital Converter chapter of the device data sheet. 1 TAD See the ADC Clock Period (TAD) vs. Device Operating Frequencies table, in the Analog-to-Digital Converter section of the device data sheet. 2010-2015 Microchip Technology Inc. DS80000501G-page 3 PIC16(L)F1938/1939 In Figure 1, 88 instruction cycles (TCY) will be required to complete the full conversion. Each TAD cycle consists of 8 TCY periods. A fixed delay is provided to stop the A/D conversion after 86 instruction cycles and terminate the conversion at the correct time as shown in the figure above. Note: The exact delay time will depend on the TAD divisor (ADCS) selection. The TCY counts shown in the timing diagram above apply to this example only. Refer to Table 3 for the required delay counts for other configurations. 2. Module: Enhanced Capture Compare PWM (ECCP) 2.1 Enhanced PWM When the PWM is configured for Full-Bridge mode and the duty cycle is set to 0%, writing the PxM<1:0> bits to change the direction has no effect on PxA and PxC outputs. Work around Increase the duty cycle to a value greater than 0% before changing directions.

Work around Increase the duty cycle to a value greater than 0% before enabling/disabling steering to port pins.

Module: Oscillator 3.1 Timer1 Gate Toggle mode 5.1 Clock Switching When Timer1 Gate Toggle mode is enabled, it is possible to measure the full-cycle length of a Timer1 gate signal. To perform this function, the Timer1 gate source is routed through a flip-flop that changes state on every incrementing edge of the gate signal. Timer1 Gate Toggle mode is enabled by setting the T1GTM bit of the T1GCON register. When working properly, clearing either the T1GTM bit or the TMR1ON bit would also clear the output value of this flip-flop, and hold it clear. This is done in order to control which edge is being measured. The issue that exists is that clearing the TMR1ON bit does not clear the output value of the flip-flop and hold it clear. When switching clock sources between INTOSC clock source and an external clock source, one corrupted instruction may be executed after the switch occurs. This issue does not affect Two-Speed Start-up or the Fail-Safe Clock Monitor operation. Work around When switching from an external oscillator clock source, first switch to 16 MHz HFINTOSC. Once running at 16 MHz HFINTOSC, configure IRCF to run at desired internal oscillator frequency. Clear the T1GTM bit in the T1GCON register to clear and hold clear the output value of the flipflop. When switching from an internal oscillator (INTOSC) to an external oscillator clock source, first switch to HFINTOSC High-Power mode (8 MHz or 16 MHz). Once running from HFINTOSC, switch to the external oscillator clock source.

Module: In-Circuit Serial Programming™ (ICSP™) 4.1 Bulk Erase Feature not available with LowVoltage Programming mode A bulk erase of the program Flash memory or data memory cannot be executed in Low-Voltage Programming mode. Work around Note: During the Two-Speed Start-up sequence, the OST is enabled to count 1024 clock cycles. After the count is reached, the OSTS bit is set, the system clock is held low until the next falling edge of the external crystal (LP, XT or HS mode), before switching to the external clock source. When an external oscillator is configured as the primary clock and Fail-Safe Clock mode is enabled (FCMEN = 1), any of the following conditions will result in the Oscillator Start-up Timer (OST) failing to restart: Method 1: If ICSP Low-Voltage Programming mode is required, use row erases to erase the program memory, as described in the Program/Verify mode section of the Programming Specification. Data memory must be over-written with the desired values. • MCLR Reset • Wake from Sleep • Clock change from INTOSC to Primary Clock Method 2: Use ICSP High-Voltage Programming mode if a bulk erase is required. Work around Only the bulk erase feature will erase program or data memory if code or data protection is enabled. Method 2 must be used if code or data protection is enabled. This anomaly will manifest itself as a clock failure condition for external oscillators which take longer than the clock failure time-out period to start. None.

DS80000501G-page 5 PIC16(L)F1938/1939 5.3 Oscillator Start-Up Timer (OSTS) bit When using an external crystal in HS mode and the 4xPLL is enabled, once the Two-Speed Start-up sequence has expired, the OSTS bit remains clear incorrectly indicating that the microcontroller is operating from the internal oscillator. This issue only occurs when the 4xPLL is enabled; when the 4xPLL is disabled, the OSTS bit operates as expected. 6. Module: Enhanced Universal Synchronous Asynchronous Receiver (EUSART) 6.1 Auto-Baud Detect When using automatic baud detection (ABDEN), on occasion, an incorrect count value can be stored at the end of auto-baud detection in the SPBRGH:SPBRGL (SPBRG) registers. The SPBRG value may be off by several counts. This condition happens sporadically when the device clock frequency drifts to a frequency where the SPBRG value oscillates between two different values. The issue is present regardless of the baud rate Configuration bit settings. Work around Use the PLL ready flag (PLLR bit of the OSCSTAT register) to determine that the microcontroller is operating from the external crystal. The PLLR bit will only be set when the clock source used by the PLL is ready; therefore, the PLLR bit will indicate when both the external crystal and the PLL are ready. Work around When using auto-baud, it is a good practice to always verify the obtained value of SPBRG, to ensure it remains within the application specifications. Two recommended methods are shown below.

For example, if the application runs at 9600 baud at 16 MHz then, the default SPBRG value would be (assuming 16-bit/Asynchronous mode) 0x67. The minimum and maximum allowed values can be calculated based on the application. In this example, a ±5% tolerance is required, so tolerance is 0x67 * 5% = 0x05.

In firmware, compute a running average of SPBRG. If the new SPBRG value falls outside the minimum or maximum limits, then use the current running average value (Average_Baud), otherwise use the auto-baud SPBRG value and calculate a new running average. For example, if the application runs at 9600 baud at 16 MHz then, the default SPBRG value would be (assuming 16-bit/Asynchronous mode) 0x67. The minimum and maximum allowed values can be calculated based on the application. In this example, a ±5% tolerance is required, so tolerance is 0x67 x 5% = 0x05.

Module: BOR Note: 7.1 BOR Reset This issue affects only the PIC16LF1938/1939 devices. These devices may undergo a BOR Reset when waking-up from Sleep and BOR is re-enabled. A BOR Reset may also occur the moment the software BOR is enabled. Under certain voltage and temperature conditions and when either SBODEN or BOR_NSLEEP is selected, the devices may occasionally reset when waking-up from Sleep or BOR is enabled. Work around Method 1: In applications where BOR use is not critical, turn off the BOR in the Configuration Word. Method 2: Set the FVREN bit of the FVRCON register. Maintain this bit on at all times. Method 3: When BOR module is needed only during run-time, use the software-enabled BOR by setting the SBODEN option on the Configuration Word. BOR should be turned off by software before Sleep, then follow the below sequence for turning BOR on after wake-up: Affected Silicon Revisions A1 A2 X X 8.1 SPI Master mode When the MSSP is used in SPI Master mode and the CKE bit is clear (CKE = 0), the Buffer Full (BF) bit and the MSSP Interrupt Flag (SSPIF) bit becomes set half an SCK cycle early. If the user software immediately reacts to either of the bits being set, a write collision may occur as indicated by the WCOL bit being set. Work around To avoid a write collision one of the following methods should be used: Method 1: Add a software delay of one SCK period after detecting the completed transfer (the BF bit or SSPIF bit becomes set) and prior to writing to the SSPBUF register. Verify the WCOL bit is clear after writing to SSPBUF. If the WCOL bit is set, clear the bit in software and rewrite the SSPBUF register. b. Turn on FVR (FVREN bit of the FVRCON register); c. Wait until FVRRDY bit is set; d. Wait 15 µs after the FVR Ready bit is set; Method 2: As part of the MSSP initialization procedure, set the CKE bit (CKE = 1). e. Manually turn on the BOR. a. Switch to internal 32 kHz oscillator immediately before Sleep; A3 8. Module: MSSP (Master Synchronous Serial Port) a.
