Ports P52–P56 are 5-bit output ports. The output structure is CMOS output.
Pins P52–P56 are also used as CRT output pins R, G, B, I, OUT respectively. The output structure
is CMOS output.
Pin P55 is also used as timer 1 overflow signal output pin TIM1 OVERFLOW. The output structure is
CMOS output.
Port P6 is an 8-bit I/O port and has basically the same functions as port P0. The output structure is
N-channel open-drain output.
Pins P60–P67 are also used as PWM output pins PWM0–PWM7. The output structure is CMOS
output.
Ports P70, P71 are 2-bit input port.
Pin P70 is also used as CRT display clock input pin OSC1.
Pin P71 is also used as CRT display clock output pin OSC2. The output structure is CMOS output.
Pins P70, P71 are also used as analog input pins AD4, AD5 respectively.
This is a horizontal synchronous signal input for CRT display.
This is a vertical synchronous signal input for CRT display.
This is a timing output pin. This pin has reset-out output function. The output structure is CMOS
output.
This is an output pin for 14-bit PWM.
The D-A pin is also used as analog input pin AD3.
Note : As shown in the memory map (Figure 5), port P0 is accessed as a memory at address 00C016 of zero page. Port P0 has the port P0
direction register (address 00C116 of zero page) which can be used to program each bit as an input (“0”) or an output (“1”). The pins
programmed as “1” in the direction register are output pins. When pins are programmed as “0,” they are input pins. When pins are
programmed as output pins, the output data are written into the port latch and then output. When data is read from the output pins, the
output pin level is not read but the data of the port latch is read. This allows a previously-output value to be read correctly even if the
output “L” voltage has risen, for example, because a light emitting diode was directly driven. The input pins float, so the values of the pins
can be read. When data is written into the input pin, it is written only into the port latch, while the pin remains in the floating state.
