The module supports a basic framed SPI protocol in
Master or Slave mode. The control bit, FRMEN,
enables framed SPI support and causes the SS1 pin to
perform the frame synchronization pulse (FSYNC)
function. The control bit, SPIFSD, determines whether

the SS1 pin is an input or an output (i.e., whether the
module receives or generates the frame synchroniza-
tion pulse). The frame pulse is an active-high pulse for
a single SPI clock cycle. When frame synchronization
is enabled, the data transmission starts only on the
subsequent transmit edge of the SPI clock.
