6.3 Port Function Control Registers
(1) Port mode registers (PM0, PM2 to PM7)
The following two types of registers control the ports.
• Port mode registers (PM0, PM2 to PM7)
• Pull-up resistor option registers (PU0, PU2 to PU7)
Cautions 1. Pins P10 to P17 are input-only pins.
These registers are used to set port input/output in 1-bit units.
PM0 and PM2 to PM7 are independently set by a 1-bit or 8-bit memory manipulation instruction.
RESET input sets registers to FFH.
When using a port pin as its alternate-function pin, set the port mode registers and output latches as shown in
Table 6-6.
2. Port 0 functions alternately as an external interrupt request input pin. If the output mode
3. If a port has an alternate function pin and it is used as an alternate output function, clear
of the port function is specified and the output level of the port is changed while interrupts
are not disabled by the external interrupt rising edge enable register (EGP) and external
interrupt falling edge enable register (EGN), the interrupt request flag is set. When the
output mode is used, therefore, the interrupt mask flag should be set to 1 beforehand.
the corresponding output latches (P0 and P2 to P7) to 0.
