(2) P10 to P15 (Port 1) … I/O
Port 1 is a 6-bit I/O port in which input or output can be set in 1-bit units.
Besides functioning as an I/O port, in control mode, P10 to P15 operate as RPU I/O and external interrupt
request input.
An operation mode of port or control mode can be selected for each bit and specified by the port 1 mode
control register (PMC1).
(a) Port mode
P10 to P15 can be set to input or output in 1-bit units using the port 1 mode register (PM1).
(b) Control mode
P10 to P15 can be set to port or control mode in 1-bit units using PMC1.
(i)
TO10, TO11 (Timer output) … Output
These pins output timer 10 and timer 11 pulse signals.
(ii) TIUD10, TIUD11 (Timer count pulse input) … Input
These are external count clock input pins to the up/down counter (timer 10, timer 11).
(iii) TCUD10, TCUD11 (Timer control pulse input) … Input
These pins input count operation switching signals to the up/down counter (timer 10, timer 11).
(iv) TCLR10, TCLR11 (Timer clear) … Input
These are clear signal input pins to the up/down counter (timer 10, timer 11).
(v) INTP100, INTP101 (Interrupt request from peripherals) … Input
These are external interrupt request input pins and timer 10 external capture trigger input pins.
(vi) INTP110, INTP111 (Interrupt request from peripherals) … Input
These are external interrupt request input pins and timer 11 external capture trigger input pins.
