Description
104
INT6
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.
FRCK
External clock input pin for freerun timer. Since this input is used as required
when selected as the external clock input for the free running timer, the port out-
put must remain off unless intentionally turned on.
PK6
General purpose input/output port.
105
INT7
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.
ATG
External trigger input for A/D converter. Since this input is used as required when
selected as an A/D activation source, the port output must remain off unless in-
tentionally turned on.
PK7
General purpose input/output port.
106 to
113
INT8 to
INT15
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.
PJ0 to PJ7
General purpose input/output port.
116
SI0
D
UART0 data input. Since this input is used as required when UART0 is in input
operation, the port output must remain off unless intentionally turned on.
PI0
General purpose input/output port.
117
SO0
D
UART0 data output. This function is enabled when the UART0 data output is en-
abled.
PI1
General purpose input/output port. This function is enabled when the data output
function of UART0 is disabled.
118
SCK0
D
UART0 clock input/output pin. This function is enabled either when clock output
enabled or when UART0 inputs the external clock signal.
PI2
General purpose input/output port. This function is enabled when UART0 is not
using the external clock signal with the UART0 clock output function disabled.
119
SI1
D
UART1 data input. Since this input is used as required when UART1 is in input
operation, the port output must remain off unless intentionally turned on.
PI3
General purpose input/output port.
120
SO1
D
UART1 data outpu. This function is enabled when the UART1 data output is en-
abled.
PI4
General purpose input/output port. This function is enabled when the data output
function of UART1 is disabled.
121
SCK1
D
UART1 clock input/output pin. This function is enabled either when clock output
enabled or when UART1 inputs the external clock signal.
PI5
General purpose input/output port. This function is enabled when UART1 is not
using the external clock signal with the UART1 clock output function disabled.
