(h) SSI11
This is a chip select input pin of serial interface CSI11.
2.2.6 P60 to P63 (port 6)
P60 to P63 function as an I/O port. These pins also function as pins for serial interface data I/O, clock I/O, and external
interrupt request input.
Input to the P60 and P61 pins can be specified through a normal input buffer or an SMBus input buffer in 1-bit units,
using port input mode register 6 (PIM6).
Output from the P60 to P63 pins can be specified as normal CMOS output or N-ch open-drain output (V
DD tolerance) in
1-bit units, using port output mode register 6 (POM6).

P63/INTP8
The following operation modes can be specified in 1-bit units.
(1) Port mode
P60 to P63 function as an I/O port. P60 to P63 can be set to input port or output port in 1-bit units using port mode
register 6 (PM6). Use of an on-chip pull-up resistor can be specified by pull-up resistor option register 6 (PU6).
(2) Control mode
P60 to P63 function as serial interface data I/O and clock I/O.
(a) SDAA0
This is a serial data I/O pin for serial interface IICA.
(b) SCLA0
This is a serial clock I/O pin for serial interface IICA.
(c) RxD6
This is a serial data input pin for serial interface UART6.
(d) TxD6
This is a serial data output pin for serial interface UART6.
(e) SCK11
This is a serial clock I/O pin for serial interface CSI11.
(f) SI11
This is a serial data input pin for serial interface CSI11.
