SC0: UART0 clock output. The clock output is valid when the UART0
clock output function setting is enabled.
PI2: General purpose input/output port. This function is valid when the
UART0 clock output function is disabled.
SI1: UART1 data input. When UART1 is set for input operation, this input
is in use at all times, so that output from other functions must be stopped
unless used intentionally.
PI3: General purpose input/output port.
SO1: UART1 data output. This function is enabled when the UART1 data
output function setting is enabled.
PI4: General purpose input/output port. This function is valid when the
UART1 data output function setting is disabled.
SC1: UART1 clock input/output. The clock output is enabled when the
UART1 clock output function setting is enabled.
PI5: General purpose input/output port. This function is valid when the
UART1 clock output function setting is disabled.
SI2: UART2 data input. When UART2 is set for input operation, this input
is in use at all times, so that output from other functions must be stopped
unless used intentionally.
PH0: General purpose input/output port.
SO2: UART2 data output. This function is enabled when the UART2 data
output function setting is enabled.
PH1: General purpose input/output port This function is enabled when
the UART2 data output function setting is disabled.
SC2: UART2 clock input/output. The clock output is enabled when the
UART2 clock output function setting is enabled.
PH2: General purpose input/output port This function is enabled when
the UART2 clock output function is disabled.
TOT0: Timer output port. This function is valid when the timer output
setting is enabled.
PH3: General purpose input/output port.This pin outputs an L level signal
at reset.
TOT1: Timer output port. This function is valid when the timer output
setting is enabled.
PH4: General purpose input/output port.This pin outputs an L level signal
at reset.
TOT2: Timer output port. This function is valid when the timer output is
enabled.
PH5: General purpose input/output port.
