Description

SRFS

(GPIOC1)

SRCK

(GPIOC2)

52 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.

Input/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.

53

Input/Output SSI Serial Receive Clock (SRCK)—This bidirectional pin provides the

serial bit rate clock for the Receive section of the SSI. The clock signal

can be continuous or gated and can be used by both the transmitter and

receiver in synchronous mode.

Input/Output Port C GPIO—This is a General Purpose I/O (GPIO) pin with the

capability of being individually programmed as input or output.

STD

After reset, the default state is GPIO input.

54

Output

SSI Transmit Data (STD)—This output pin transmits serial data from the

SSI Transmitter Shift Register.

(GPIOC3)

STFS

(GPIOC4)

Input/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.

55

Input

SSI Serial Transmit Frame Sync (STFS)—This bidirectional pin is used

by the Transmit section of the SSI as frame sync I/O or flag I/O. The

STFS can be used by both the transmitter and receiver in synchronous

mode. It is used to synchronize data transfer and can be an input or

output pin.

Input/Output Port C GPIO—This is a General Purpose I/O (GPIO) pin with the

capability of being individually programmed as input or output.

STCK

(GPIOC5)

After reset, the default state is GPIO input.

56 Input/ Output SSI Serial Transmit Clock (STCK)—This bidirectional pin provides the

serial bit rate clock for the transmit section of the SSI. The clock signal

can be continuous or gated. It can be used by both the transmitter and

receiver in synchronous mode.

Input/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.
