2.3 Description of Pin Functions
(1) P00 to P07 (Port 0) ··· 3-state I/O
44
P00 to P07 constitute an 8-bit I/O port that can be set to input or output in 1-bit units.
P00 to P07 can also function as an NMI input, external interrupt request inputs, external trigger for the A/D
converter, and external trigger for the real-time output port. The valid edges of the NMI and INTP0 to INTP6 pins
are specified by the EGP0 and EGN0 registers.
(a) Port function
(b) Alternate functions
P00 to P07 can be set to input or output in 1-bit units using the port 0 mode register (PM0).
(i)
(ii) INTP0 to INTP6 (Interrupt request from peripherals) ··· input
(iii) ADTRG (AD trigger input) ··· input
(iv) RTPTRG (Real-time output port trigger input) ··· input
NMI (Non-maskable interrupt request) ··· input
This is a non-maskable interrupt request signal input pin.
These are external interrupt request input pins.
This is the A/D converter’s external trigger input pin. This pin is controlled by the A/D converter mode
register (ADM).
This is the real-time output port’s external trigger input pin. This pin is controlled by the real-time output
port control register (RTPC).
