I/O
Circuit
Type
UART1 data input. Since this input is used as required when UART1 is performing
input operation, the port output must remain off unless used intentionally.
D
General-purpose I/O port. This port is enabled when UART1 data input is disabled.
UART1 data output. This function is enabled when UART1 data output is enabled.
D
General-purpose I/O port. This function is enabled when UART1 data output is
disabled.
UART1 clock input/output. This function is enabled when UART1 clock output is
enabled.
D
General-purpose I/O port. This function is enabled when UART1 clock output is
disabled.
External interrupt input. Since this input is used as required when the corresponding
external interrupt is enabled, the port output must remain off unless used
intentionally.
E
General-purpose I/O port. This function is enabled when external interrupt input is
disabled.
External interrupt input. Since this input is used as required when the corresponding
external interrupt is enabled, the port output must remain off unless used
intentionally.
E
General-purpose I/O port. This function is enabled when external interrupt input is
disabled.
C General-purpose I/O port. This port is enabled in single-chip mode.
Reload timer 0 external trigger input. Since this input is used as required when
trigger input is enabled, the port output must remain off unless used intentionally.
C
General-purpose I/O port. This function is enabled when reload timer 0 external
clock input is disabled.
Reload timer 1 external trigger input. Since this input is used as required when
trigger input is enabled, the port output must remain off unless used intentionally.
C
General-purpose I/O port. This function is enabled when reload timer 1 external
clock input is disabled.
