I/O PORTS
(1) Port P0
Port P0 is an 8-bit I/O port with N-channel open-drain output.
As shown in the memory map (Figure 3), port P0 can be ac-
cessed at zero page memory address 00C016.
Port P0 has a directional register (address 00C116) which can be
used to program each individual bit as input (“0”) or as output
(“1”). If the pins are programmed as output, the output data is
latched to the port register and then output. When data is read
from the output port the output pin level is not read, only the
latched data in the port register is read. This allows a previously
output value to be read correctly even though the output voltage
level is shifted up or down.
Pins set as input are in the floating state and the signal levels can
thus be read. When data is written into the input port, the data is
latched only to the port latch and the pin still remains in the float-
ing state.
Ports P00-P03 are in common with 6-bit PWM outputs PWM4-
PWM7. For the M37211M2, ports P00 and P01 are in common
with 6-bit PWM outputs PWM4 and PWM5.
(2) Port P1
Port P1 has basically the same function as port P0 except the
output structure is CMOS output. But, pins P15-P17 are input
ports and in common with analog input pins A-D1-A-D3.
(3) Port P2
Port P2 has basically the same function as port P1.
(4) Port P3
Port P3 are a 2-bit I/O port and a 4-bit input port with function
similar to port P2, but the output structure of P30, P31 is CMOS
output.
P32, P33 are in common with the external clock input pins of timer
2 and 3.
P34, P35 are in common with the external interrupt input pins
INT1, INT2 and P35 with the analog input pin of A-D comparator
A-D4.
(5) Port P4
Port P4 are a 2-bit I/O port and a 1-bit input port with function
similar to port P2, but the output structure is N-channel open-
drain output.
When a serial I/O function is selected, P40-P42 are in common
with pins SOUT, SCLK and SIN.
(6) OSC1, OSC2 pins
Clock input/output pins for CRT display function.
(7) HSYNC, VSYNC pins
HSYNC is a horizontal synchronizing signal input pin for CRT dis-
play.
VSYNC is a vertical synchronizing signal input pin for CRT display.
(8) R, G, B, OUT pins
This is an 4-bit output pin for CRT display and in common with
P52-P55.
(9) Port P6
Port P6 is an 4-bit output port with function similar to port P0, but
the output structure is N-channel opendrain output.
This port is in common with 6-bit PWM output pin PWM0-PWM3.
(10) D-A pin
This is a 14-bit PWM output pin.
