2. FUNCTIONS
2.1 Pipeline Processing
This section describes the µ PD77017 pipeline processing.
2.1.1 Outline
The µPD77017 basic operations are executed in following 3-stage pipeline.
(1) instruction fetch; if
(2) Instruction decoding; id
(3) execution; ex
When the µ PD77017 operates a result of a instruction just executed before, the data is input to ALU in parallel
with written back to general registers. Pipeline processing actualizes programming without delay time to execute
instructions and write back data. Three successive instructions and their processing timing are shown below.

2.1.2 Instructions with Delay
The following instructions have delay time in execution.
(1) Instructions to control interrupt
2 instruction cycles have been taken between instruction fetch and execution.
(2) Inter-register transfer instructions and immediate data set instructions
When data is set in data pointer, it needs 2 instruction cycles before the data is valid.

µPD77015, 77017, 77018
2.2 Program Control Unit
Program control unit controls not only count up of program counter in normal operation, but loop, repeat,
branch, halt and interrupt.
In addition to loop stack of loop 4 level and program stack of 15 level, software stack can be used for multiloop and multi-interrupt/subroutine call.
The µPD77017 has external 4 interruptions and internal 6 interruptions from peripheral, and specifies interrupt
enable or disable independently.
The HALT and STOP instructions cause the µ PD77017 to place in low power standby mode.
When the HALT instruction is executed, power consumption decreases. HALT mode is released by interrupt
input or hardware reset input. It takes several system clock to recover.
When the STOP instruction is executed, power consumption decreases. STOP mode is released by hardware
reset input. It takes a few ms to recover.
2.3 Operation Unit
Operation unit consists of the following five parts.
– 40 bits general register × 8 for data load/store and input/output of operation data
– 16 bits × 16 bits + 40 bits → 40 bits multiply accumulator
– 40 bits Data ALU
– 40 bits barrel shifter
– SAC: shifter and count circuit.
Standard word length is 40 bits to make overflow check and adjustment easy, and to accumulate the result
of 16 bits × 16 bits multiplication correctly.

2.3.1 General register (R0 to R7)
The µ PD77017 has eight 40 bits registers for operation input/output and load/store with memory. General
register consists of the following three parts.
– R0L to R7L (bit 15 to bit 0)
– R0H to R7H (bit 31 to bit 16)
– R0E to R7E (bit 39 to bit 32)

2.3.2 MAC: Multiply ACcumulator
MAC multiplies a pair of 16 bits data, and adds or subtract the result and 40 bits data. MAC outputs 40 bits
data.
MAC operates three types of multiplication: signed data × signed data, signed data × unsigned data and
unsigned data × unsigned data.
Result of multiplication and 40 bits data for addition can be added after 1 or 16 bits arithmetic shift right.
2.3.3 ALU: Arithmetic Logic Unit
ALU performs arithmetic operation and logic operation. Both input/output data are 40 bits.
2.3.4 BSFT: Barrel ShiFTer
BSFT performs shift right/left operation. Both input/output data are 40 bits. There are two types of shift right
operations; arithmetic shift right which sign is extended, and logic shift right which is input 0 in MSB first.

2.4.3 Data Memory Addressing
There are following two types of data memory addressing.
• Direct addressing
The address is specified in the instruction field.
• Indirect addressing
The address is specified by the data pointer (DP). DP can get a bit reverse before addressing. It can
update the DP value after accessing data memory.
2.5 On-chip Peripheral Circuit
The µ PD77017 includes serial interface, host interface, general input/output ports and wait cycle registers.
They are mapped in both X and Y memory areas, and are accessed as memory mapped I/O by the µPD77017
CPU.
2.5.1 Serial Interface Outline
The µ PD77017 has 2 channel serial interfaces. Serial I/O clock must be provided from external. Frame length
can be programmed independently to be 8 bits or 16 bits. MSB first or LSB first can also be selected. Data is
input/output by hand shaking for an external device, and by interrupts, polling or wait function in internal.
2.5.2 Host Interface Outline
The µ PD77017 has 8 bits parallel ports as host interface to input/output data to and from host CPU and DMA
controller. When an external device accesses host interface, HA0 and HA1 pins; which are host address input
pins; specifies bit 15 to bit 8 and bit 7 to bit 0. The µPD77017 includes 3 registers consisting of 16 bits, which
are dedicated for input data, output data and status. The µ PD77017 has three types of interface method for
internal and external data; interrupts, polling and wait function.
2.5.3 General Input/output Ports Outline
General input/output ports consist of 4 bits. User can set each port as input or output. The µPD77017 includes
two registers. One is 4 bits register for input/output data, and the other is 16 bits for control.
2.5.4 Wait Cycle Register
The wait cycle registers consist of 16 bits. It is used to set wait cycle number when external memory is
accessed. When external data memory area (C000H - FFFFH) is accessed, 0, 1, 3, or 7 wait cycle can be set.
When external data memory area is accessed, wait cycle can be also set by WAIT pin.

Cautions 1. When using system clock oscillator, wire the portion enclosed in broken lines in the figure
as follows to avoid adverse influences on the wiring capacitance:
• Keep the wiring length as short as possible.
• Do not cross the wiring over the other signal lines.
• Do not route the wiring in the vicinity of lines through which a high fluctuating current
flows.
• Always keep the ground point of the capacitor of the oscillator circuit at the same
potential as GND.
• Do not connect the power source pattern through which a high current flows.
• Do not extract signals from the oscillator.
2. When using ceramic resonator or crystal resonator, frequency multiple rate should be
specified to as 1 by mask option. The device does not operate in other frequency multiple
rate.

Note 1. The t w(RL) indicates a time between crystal resonator or oscillator starts to provide clock and PLL
becomes stable. The t w(RL) depends on the rating of crystal resonator or oscillator. At power on, the
t w(RL) is measured after the point that power supply voltage reaches to 0.8 VDD .

Notes for Serial Clock
Serial clock inputs SCK1 and SCK2 are sensitive to any kind of interfering signals (noise on power supply,
induced voltage, etc.). Spurious signals can cause malfunction of the device. Special care for the serial clock
design should be taken. Careful grounding, decoupling and short wiring of SCK1 and SCK2 are recommended.
Intersection of SCK1 and SCK2 with other serial interface lines or close wiring to lines carrying high frequency
signals or large changing currents should be avoided.
It considers for the serial clock to make a waveform stable especially about the rising and falling.
Example 1. good example
Straight rising form and falling
form
Example 2. no good example
It doesn’t bound. It doesn’t make
noise one above another.
Example 3. no good example
It doesn’t make a stair stepping.

NOTES FOR CMOS DEVICES
1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note: Strong electric field, when exposed to a MOS device, can cause destruction
of the gate oxide and ultimately degrade the device operation. Steps must
be taken to stop generation of static electricity as much as possible, and
quickly dissipate it once, when it has occurred. Environmental control must
be adequate. When it is dry, humidifier should be used. It is recommended
to avoid using insulators that easily build static electricity. Semiconductor
devices must be stored and transported in an anti-static container, static
shielding bag or conductive material.
All test and measurement tools
including work bench and floor should be grounded. The operator should
be grounded using wrist strap. Semiconductor devices must not be touched
with bare hands. Similar precautions need to be taken for PW boards with
semiconductor devices on it.
2 HANDLING OF UNUSED INPUT PINS FOR CMOS
Note: No connection for CMOS device inputs can be cause of malfunction. If no
connection is provided to the input pins, it is possible that an internal input
level may be generated due to noise, etc., hence causing malfunction. CMOS
devices behave differently than Bipolar or NMOS devices. Input levels of
CMOS devices must be fixed high or low by using a pull-up or pull-down
circuitry.
Each unused pin should be connected to VDD or GND with a
resistor, if it is considered to have a possibility of being an output pin. All
handling related to the unused pins must be judged device by device and
related specifications governing the devices.
3 STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note: Power-on does not necessarily define initial status of MOS device. Production
process of MOS does not define the initial operation status of the device.
Immediately after the power source is turned ON, the devices with reset
function have not yet been initialized. Hence, power-on does not guarantee
out-pin levels, I/O settings or contents of registers. Device is not initialized
until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.

The export of this product from Japan is regulated by the Japanese government. To export this product may be prohibited
without governmental license, the need for which must be judged by the customer. The export or re-export of this product
from a country other than Japan may also be prohibited without a license from that country. Please call an NEC sales
representative.
No part of this document may be copied or reproduced in any form or by any means without the prior written
consent of NEC Corporation. NEC Corporation assumes no responsibility for any errors which may appear in
this document.
NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property
rights of third parties by or arising from use of a device described herein or any other liability arising from use
of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other
intellectual property rights of NEC Corporation or others.
While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,
the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or
property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety
measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
"Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a
customer designated "quality assurance program" for a specific application. The recommended applications of
a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device
before using it in a particular application.
Standard: Computers, office equipment, communications equipment, test and measurement equipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
Specific: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality grade,
they should contact an NEC sales representative in advance.
Anti-radioactive design is not implemented in this product.
