P40 to P47 function as an 8-bit I/O port. These pins also function as external interrupt request input, serial
Input to the P43 and P44 pins can be specified through a normal input buffer or a TTL input buffer in 1-bit units
Output from the P43 and P45 pins can be specified as normal CMOS output or N-ch open-drain output (V
The following operation modes can be specified in 1-bit units.
P30 and P31 function as external interrupt request input, timer I/O, and real-time counter correction clock output.

(b) TI03
(c) TO03
(d) RTC1HZ
P40 to P47 function as an 8-bit I/O port. P40 to P47 can be set to input or output port in 1-bit units using port
mode register 4 (PM4). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 4
(PU4).
Be sure to connect an external pull-up resistor to P40 when on-chip debugging is enabled (by using an option
byte).
P40 to P47 function as serial interface data I/O, clock I/O, external interrupt request input, data I/O for a flash
memory programmer/debugger, clock output, and timer I/O.
(a) INTP1, INTP2
(b) TOOL0
These are the external interrupt request input pins for which the valid edge (rising edge, falling edge, or both
rising and falling edges) can be specified.
This is a pin for inputting an external count clock/capture trigger to 16-bit timer 03.
This is a timer output pin from 16-bit timer 03.
This is a real-time counter correction clock (1 Hz) output pin.
These are the external interrupt request input pins for which the valid edge (rising edge, falling edge, or both
rising and falling edges) can be specified.
This is a data I/O pin for a flash memory programmer/debugger.
Be sure to pull up this pin externally when on-chip debugging is enabled (pulling it down is prohibited).
