(g) SO11
This is a serial data output pin for serial interface CSI11.
(h) INTP8 to INTP11
These are external interrupt request input pins for which the valid edge (rising edge, falling edge, or both rising
and falling edges) can be specified.
2.2.7 P70 to P75 (port 7)
P70 to P75 function as an I/O port. These pins also function as pins for A/D converter analog input and key interrupt
input pins.

The following operation modes can be specified in 1-bit units.
(1) Port mode
P70 to P75 function as an I/O port. P70 to P75 can be set to input or output port in 1-bit units using port mode
register 7 (PM7). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 7 (PU7) in
78K0/KC2-L.
(2) Control mode
P70 to P75 function as pins for A/D converter analog input and key interrupt input pins.
(a) ANI8 to ANI10
These are the A/D converter analog input pins. When using this pin as analog input pin, refer to (5) ANI0/P20 to
ANI7/P27, ANI8/P10 to ANI10/P12, and ANI8/P70 to ANI10/P72 in 12.6 Cautions for A/D Converter.
(b) KR0 to KR5
These are the key interrupt input pins
