(g) SSI11
This is a chip select input pin of serial interface CSI11.
2.2.2 P10 to P17 (port 1)
P10 to P17 function as an I/O port. These pins also function as pins for A/D converter analog input, operational
amplifier I/O, external interrupt request input, serial interface data I/O, clock I/O, and timer I/O.

Note Products with operational amplifier only
The following operation modes can be specified in 1-bit units.
(1) Port mode
P10 to P17 function as an I/O port. P10 to P17 can be set to input or output port in 1-bit units using port mode
register 1 (PM1). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 1 (PU1).
(2) Control mode
P10 to P17 function as A/D converter analog input, operational amplifier I/O, external interrupt request input, serial
interface data I/O, clock I/O, and timer I/O.
(a) ANI8 to ANI10
These are A/D converter analog input pins. When using these pins as analog input pins, refer to (5) ANI0/P20
to ANI7/P27, ANI8/P10 to ANI10/P12 in 12.6 Cautions for A/D Converter.
Cautions 1. ANI8/P10 to ANI10/P12 are set in the digital input mode after release of reset.
2. Make the AV
REF pin the same potential as the VDD pin when ANI8 to ANI10 are used.
(b) AMP1+, AMP1-
These are operational amplifier 1 input pins.
(c) AMP1OUT
This is an operational amplifier 1 output pin.
(d) SI10
This is a serial data input pin of serial interface CSI10.
