The RX_TRIGx external trigger can be used to initiate FSITX transmission. RX_TRIG0 must be used if TDM mode (multi-node configuration) is required. RX_TRIG0 must be used as the trigger source for start of transmission while the programmable stretch width RX_TRIG0 signal is used as the SEL_TDM_PATH signal (which decides whether the local FSITX is active or put in bypass mode).
The signal source for the RX_TRIGx signal is selected through the RX_TRIG_CTRL_x.TRIG_SEL bits, as listed in Table 7-184.

The RX_TRIGx signals can optionally be delayed (this can be used in TDM scenarios) through the RX_TRIG_CTRL_x.TRIG_DLY.
