(2) P10 to P13 (Port 1) ··· 3-state I/O
P10 to P13 function as a 4-bit I/O port that can be set to input or output in 1-bit units.
Besides functioning as an I/O port, in the control mode, these pins operate as I/O for the real-time pulse unit
(RPU), external interrupt request inputs, and a PWM output.
The operation mode can be set to port or control mode in 1-bit units, specified by the port 1 mode control
register (PMC1).
(a) Port mode
P10 to P13 can be set to input or output in 1-bit units using the port 1 mode register (PM1).
(b) Control mode
P10 to P13 can be set to port/control mode in 1-bit units using the PMC1 register.
(i)
PWM1 (Pulse width modulation) ··· output
This pin outputs the PWM pulse signal.
(ii) TI010 (Timer input) ··· input
This is the external count clock input pin for timer C1.
(iii) TO01 (Timer output) ··· output
This pin outputs the pulse signal for timer C1.
(iv) INTP010, INTP011 (Interrupt request from peripherals) ··· input
These are external interrupt request input pins and the external capture trigger input pins for timer
C1.
