P43
G
(STBC)
General-purpose I/O port
When I/O expansion serial is operating, the data at the pin is
used as the serial input (SIN1).
Can be set as an open-drain output port (OD43 = “1”) by the
open-drain control register (ODR4). The setting does not apply
for ports set as inputs (D43 = “0”: invalid at the input setting).
SIN1
Functions as the serial input for I/O expansion serial data.

P44
F
(STBC)
General-purpose I/O port
Functions as the SOT1 pin if the SOE bit in the UMC register is
“1”.
Can be set as an open-drain output port (OD44 = “1”) by the
open-drain control register (ODR4). The setting does not apply
for ports set as inputs (D44 = “0”: invalid at the input setting).
SOT1
Functions as the output pin (SOT1) for I/O expansion serial
data.

P45
G
(STBC)
General-purpose I/O port
When I/O expansion serial is operating in external shift clock
mode, the data at the pin is used as the clock input (SCK1).
Also, functions as the SCK1 pin if the SOE bit in the UMC
register is “1”.
Can be set as an open-drain output port (OD45 = “1”) by the
open-drain control register (ODR4). The setting does not apply
for ports set as inputs (D45 = “0”: invalid at the input setting).
SCK1
Functions as the I/O expansion serial clock I/O pin (SCK1).

P46
F
(STBC)
General-purpose I/O port
Can be set as an open-drain output port (OD46 = “1”) by the
open-drain control register (ODR4). The setting does not apply
for ports set as inputs (D46 = “0”: invalid at the input setting).
ADTG
Functions as the external trigger input pin for the A/D
converter.

P47
F
(STBC)
General-purpose I/O port
Can be set as an open-drain output port (OD47 = “1”) by the
open-drain control register (ODR4). The setting does not apply
for ports set as inputs (D47 = “0”: invalid at the input setting).
