Figure 43-13. Transmit and Receive Frame Format in Edge/Pulse Start Modes
Note: 1. Example of input on falling edge of TF/RF.
Figure 43-14. Transmit Frame Format in Continuous Mode
Note: 1. STTDLY is set to 0. In this example, SSC_THR is loaded twice. FSDEN value has no effect on the transmis-
sion. SyncData cannot be output in continuous mode.
