Input/Output
SSI Receive Data (SRD)—This input pin receives serial data and transfers the
data to the SSI Receive Shift Receiver.
Port C GPIO—This is a General Purpose I/O (GPIO) pin with the capability of
being individually programmed as input or output.
After reset, the default state is GPIO input.
SRFS
(GPIOC1)
52
Input/ Output
Input/Output
SSI Serial Receive Frame Sync (SRFS)—This bidirectional pin is used by the
receive section of the SSI as frame sync I/O or flag I/O. The STFS can be used
only by the receiver. It is used to synchronize data transfer and can be an input
or an output.
Port C GPIO—This is a General Purpose I/O (GPIO) pin with the capability of
being individually programmed as input or output.
After reset, the default state is GPIO input.
