DESCRIPTION
These are single-chip 16-bit microcomputers designed with high-performance CMOS silicon gate technology, including the internal flash
memory and, being packaged in 64-pin plastic molded QFP or shrink
plastic molded DIP. These microcomputers support the 7900 Series
instruction set, which are enhanced and expanded instruction set
and are upper-compatible with the 7700/7751 Series instruction set.
The CPU of these microcomputers is a 16-bit parallel processor that
can also be switched to perform 8-bit parallel processing. Also, the
bus interface unit of these microcomputers enhances the memory
access efficiency to execute instructions fast. Therefore, these microcomputers are suitable for office, business, and industrial equipment controller that require high-speed processing of large data.
Also, they are suitable for motor-control equipment since each of
them includes the motor control circuit.
For the internal flash memory, single-power-supply programming
and erasure, using a PROM programmer or the control by the central processing unit (CPU), is supported. Also, each of these microcomputers has the memory area dedicated for storing a certain
software which controls programming and erasure (reprogramming
control software). Therefore, on these microcomputers, the program
can easily be changed even after they are mounted on the board.

When using the PLL frequency multiplier, connect this pin to the filter circuit. When
not using the PLL frequency multiplier, this pin should be left open.
Power supply input pins for the A-D and D-A converters. Connect AVcc to Vcc, and
AVss to Vss externally.
This is the reference voltage input pin for the A-D and D-A converters.
Port P1 is an 8-bit I/O port. This port has an I/O direction register, and each pin can
be programmed for input or output. These pins enter the input mode ar reset. These
pins also function as I/O pins of UART0, 1.
In addition to having the same functions as port P1, these pins function as I/O pins
for timers A4 and A9. Also, they can be programmed to function as input pins for timers B0 to B2.
In addition to having the same functions as port P1, these pins function as I/O pins
for timers A5 to A8. Also, they function as output pins for motor drive waveform.
In addition to having the same functions as port P1, these pins function as input pins
for INT
1 to INT3 and INT5 to INT7. Also, pins P55 to P57 function as input pins for tim-
ers B0 to B2 and as input pins for position data in the three-phase waveform mode;
and pins P5
In addition to having the same functions as port P1, these pins function as I/O pins
for timers A0 to A3. Also, they function as motor drive waveform output pins.
In addition to having the same functions as port P1, these pins function as input pins
for the A-D converter. Also, P7
In addition to having the same functions as port P1, these pins function as input pins
for the A-D converter. Also, these pins function as I/O pins for UART2, and pin P8
functions as an output pin for the D-A converter.
This pin has the function to forcibly place port P4 pins in the input mode. Also, this
pin functions as an input pin for INT
forcibly cuts off a motor drive waveform output.
This pin has the function to forcibly place port P6 pins in the input mode. Also, this
pin functions as an input pin for INT
