4.2.1 Port 0
using port mode register 0 (PM0). When the P00 to P07 pins are used as an input port, use of an on-chip pull-up
resistor can be specified in 1-bit units by pull-up resistor option register 0 (PU0).
using port input mode register 0 (PIM0).
port output mode register 0 (POM0).
external wait signal input.
Port 0 is an 8-bit I/O port with an output latch. Port 0 can be set to the input mode or output mode in 1-bit units
Input to the P03 and P04 pins can be specified through a normal input buffer or a TTL input buffer in 1-bit units
Output from the P02 to P04 pins can be specified as N-ch open-drain output (V
This port can also be used for timer I/O, serial interface data I/O, clock I/O, internal system clock output, and
Reset signal generation sets port 0 to input mode.
Figures 4-2 to 4-8 show block diagrams of port 0.
Cautions 1. To use P01/TO00 as a general-purpose port, set bit 0 (TO00) of timer output register 0 (TO0)
2. To use P02/SO10/TxD1, P03/SI10/RxD1/SDA10, or P04/SCK10/SCL10 as a general-purpose
and bit 0 (TOE00) of timer output enable register 0 (TOE0) to “0”, which is the same as their
default status setting.
