Port P5 And Port P6 Direction Registers - Renesas 7700 FAMILY User Manual

TIMER A
5.2 Block description

5.2.5 Port P5 and port P6 direction registers

The I/O pins of Timers A0 to A3 are shared with port P5, and the I/O pins of Timer A4 are shared with
port P6. When using these pins as Timer Ai's input pins, set the corresponding bits of the port P5 and port
P6 direction registers to "0" to set these ports for the input mode. When used as Timer Ai's output pins,
these pins are forcibly set to output pins of Timer Ai regardless of the direction registers's contents. Figure
5.2.5 shows the relationship between the port P5 and port P6 direction registers and the Timer Ai's I/O
pins.
