Description
90
SI7
D
Data input for serial I/O 7. Since this input is used as required when serial I/O 7
is in input operation, the port output must remain off unless intentionally turned
on.
AIN1
Up/down timer input. Since this input is used as required when enabled, the port
output must remain off unless intentionally turned on.
TRG3
External trigger input for PPG timer 3. Since this input is used as required when
enabled, the port output must remain off unless intentionally turned on.
PM3
General purpose I/O. This function is available a port when the serial I/O, up/
down timer, and PPG timer outputs are not in use.
91
SO7
D
Data output for serial I/O 7. This function is enabled when the serial I/O 7 data
output is enabled.
BIN1
Up/down timer input. Since this input is used as required when enabled, the port
output must remain off unless intentionally turned on.
TRG4
External trigger input for PPG timer 4. Since this input is used as required when
enabled, the port output must remain off unless intentionally turned on.
PM4
General purpose I/O. This function is available a port when the serial I/O, up/
down timer, and PPG timer outputs are not in use.
92
SCK7
D
Clock input/output for serial I/O5. This function is enabled when serial I/O 7 is us-
ing the external shift clock mode, or serial I/O 5 clock output function is enabled.
ZIN1
Up/down timer input. Since this input is used as required when enabled, the port
output must remain off unless intentionally turned on.
TRG5
External trigger input for PPG timer 5. Since this input is used as required when
enabled, the port output must remain off unless intentionally turned on.
PM5
General purpose I/O. This function is available a port when the serial I/O, up/
down timer, and PPG timer outputs are not in use.
94
SDA
F
Clock input/output pin for I2C bus. This function is enabled when the I2C system
is enabled for operation in standard mode. The port output must remain off unless
intentionally turned on. (Open drain input)
PL0
General purpose input/output port. This function is available as a port when the
I2C system is disabled for operation. (Open drain input)
95
SCL
F
Clock input/output pin for I2C bus. This function is enabled when the I2C system
is enabled for operation in standard mode. The port output must remain off unless
intentionally turned on. (Open drain input)
PL1
General purpose input/output port. This function is available as a port when the
I2C system is disabled for operation. (Open drain input)
98 to 103
INT0 to
INT5
E
External interrupt input. Since this input is used as required when the correspond-
ing external interrupt is enabled, the port output must remain off unless intention-
ally turned on.
PK0 to PK5
General purpose input/output port.
