7.4.4 Signal Descriptions
7.4.4.1 External Signals
7.4.4.1.1
STCK — SSI Transmit Clock
This pin can be configured as either an input or an output pin. This clock signal is used by the transmitter
and can be either continuous or gated. During gated clock mode, the STCK pin is active only during the
transmission of data, otherwise, it is inactive (low). In synchronous mode, this pin is used by both the
transmit and receive sections.
7.4.4.1.2
STFS — SSI Transmit Frame Sync
This pin can be configured as either an input or an output pin. The frame sync is used by the transmitter to
synchronize the transfer of data. The frame sync signal can be one bit or one word in length. The start of the
frame sync can occur one bit before the transfer of data or right at the start of the data transfer.
In synchronous mode, this pin is used by both the transmit and receive sections. In gated clock mode, frame
sync signals are not used.
7.4.4.1.3
SRCK — SSI Receive Clock
This pin can be configured as either an input or an output pin. This clock signal is used by the receiver and
can be either continuous or gated. During gated clock mode, the SRCK pin is active only during the
reception of data, otherwise, it is inactive (low).
In synchronous mode, this pin is not used and can be configured as a GPIO pin.
7.4.4.1.4
SRFS — SSI Receive Frame Sync
This pin can be configured as either an input or an output pin. The frame sync is used by the receiver to
synchronize the transfer of data. The frame sync signal can be one bit or one word in length. The start of the
frame sync can occur one bit before the transfer of data or right at the start of the data transfer.
In synchronous mode, this pin is not used and can be configured as a GPIO pin.
7.4.4.1.5
STXD — SSI Transmit Data
This pin transmits data from the serial transmit shift register (STSR). The STXD pin is an output pin when
data is being transmitted and is inactive (high-Z) between data word transmissions.
7.4.4.1.6
SRXD — SSI Receive Data
This pin is used to bring serial data into the receive data shift register (RXSR).
