18.3.2 Texas Instruments Frame Format

For the Texas Instruments DSP-compatible synchronous serial interface frame format, the

SSPFRM pin is pulsed for one serial clock period stating at its rising edge, prior to each

frame's transmission. For this frame format, the SSP outputs data on the rising edge of the

clock and latches input data on the rising edge of the clock.

Figure 18-7 shows the Texas Instruments DSP format for a single transfer. Figure 18-8

shows the same format for continuous transfers.
