TDRE clearance. To transmit with a different transmit mode after clearing the relevant mode,
the procedure must be started again from initialization. Figure 15.39 shows a sample flowchart
for mode transition during transmission. Port pin states are shown in figures 15.40 and 15.41.
Operation should also be stopped (by clearing TE, TIE, and TEIE to 0) before making a
transition from transmission by DTC transfer to module stop mode, software standby mode,
watch mode, subactive mode, or subsleep mode transition. To perform transmission with the
DTC after the relevant mode is cleared, setting TE and TIE to 1 will set the TXI flag and start
DTC transmission.
