CHAPTER 2 PIN FUNCTIONS
(h) INTP9, INTP11
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.
Caution To use P80/SCK00/INTP11, P81/RxD0/SI00/INTP9, and P82/SO00/TxD0, as a general-purpose port,
note the serial array unit 0 setting. For details, refer to Table 14-5 Relationship Between Register
Settings and Pins (Channel 0 of unit 0: CSI00, UART0 Reception).
2.2.10 P90 to P97
P90 to P97 function as an I/O port. This port can also be used for segment output of LCD controller/driver.

The following operation modes can be specified in 1-bit units.
(1) Port mode
P90 to P97 function as an I/O port. P90 to P97 can be set to input or output port in 1-bit units using port mode
register 9 (PM9). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 9 (PU9).
(2) Control mode
P90 to P97 function as segment output of LCD controller/driver (SEGxx).
