2.2 Description of Pin Functions
2.2.1 P00 to P03 (Port 0)
signals, a timer output stop external signal and an external trigger signal of the A/D converter.
2.2.2 P10 to P17 (Port 1)
also serve as the analog input pins of the A/D converter.
42
These pins constitute a 4-bit I/O port, port 0. In addition, these pins are also used to input external interrupt request
Port 0 can be set in the following operation modes in 1-bit units.
(1) Port mode
(2) Control mode
These pins constitute an 8-bit input port, port 1. In addition to the general-purpose input port function, these pins
(1) Port mode
(2) Control mode
In this mode, P00 to P03 function as a 4-bit I/O port which can be set to input or output in 1-bit units by using
port mode register 0 (PM0). An internal pull-up resistor can be used if so specified by pull-up resistor option
register 0 (PU0).
In this mode, P00 to P03 are used to input external interrupt requests, a timer output stop external signal, and
an external trigger signal of the A/D converter.
(a) INTP0 to INTP3
(b) TOFF7
(c) ADTRG
In this mode, P10 to P17 function as an 8-bit input port.
In this mode, P10 to P17 function as the analog input pins (ANI0 to ANI7) of the A/D converter.
falling edge, and both rising and falling edges). INTP2 also functions as an external trigger signal input
pin of the real-time output port when a valid edge is input.
These pins are external interrupt request input pins for which the valid edge can be specified (rising edge,
External input pin to stop timer output (TO70 to TO75).
External trigger signal input pin of the A/D converter.
