transfers the data to the SCI receive shift register. Input data can be
sampled on either the positive edge or on the negative edge of the
receive clock, depending on how the SCI control register is
programmed.
Port C GPIO 0 (PC0)—This signal is a GPIO signal called PC0
when the SCI RXD function is not being used.
After reset, the default state is GPIO input.
the SCI transmit shift register. In the default configuration, the
data changes on the positive clock edge and is valid on the
negative clock edge. The user can reverse this clock polarity by
programming the SCI control register appropriately.
Port C GPIO 1 (PC1)—This signal is a GPIO signal called PC1
when the SCI TXD function is not being used.
After reset, the default state is GPIO input.
clock from which the receive or transmit baud rate is derived in
the Asynchronous mode, and from which data is transferred in
the Synchronous mode. The direction and function of the signal
is defined by the RCM bit in the SCI+ Clock Control Register
(SCCR).
Port C GPIO 2 (PC2)—This signal is a GPIO signal called PC2
when the SCI SCLK function is not being used.
After reset, the default state is GPIO input.
