Circuit
Type
C
General-purpose I/O port.
UART2 data input. Since this input is used as required when UART2 is performing
input operation, the port output must remain off unless used intentionally.
D
General-purpose I/O port. This port is enabled when UART2 data input is disabled.
UART2 data output. This function is enabled when UART2 data output is enabled.
D
General-purpose I/O port. This port is enabled when UART2 data output is disabled.
UART2 clock input/output. This function is enabled when UART2 clock output is
enabled.
D
General-purpose I/O port. This function is enabled when UART2 clock output is
disabled.
