3.5.4 Port 3 (P30 ~ P37)
Port 3 is an 8-bit general-purpose I/O port (P3: memory
address FF87H). The I/O is selected by the control register
(P3CR: memory address FF88H) in bit basis. Port 3 also has a
programmable pull-up resistor which functions when the output
latch register is “1”. By resetting, all bits are initialized to “1”,
and the control register to “0”. As a result, Port 3 turns to the
pull-up input port.
In addition to the I/O port function, Port 3 has the external
interrupt request input, timer/event counter clock input, and
timer output internal serial interface functions.

P30 ~ P33
P30 ~ P33 are general-purpose I/O ports, shared
between
external interrupt request input pins (INT0,
INT1) and timer/event counter clock input pins (TI0,
TI2
).
These ports have zero-cross detection circuits, which
are connected to an external capacitor. This zero-cross
detection disable/enable is specified by the function
register (P3FR: memory address FF98H). When this
register is initialized to “0”, by resetting, the zero-cross
detection becomes disabled.
