In Stop mode, if the Transmitter Stop Enable (TCSR[STOPE]) bit is clear, the transmitter
is disabled after completing the current transmit frame, and, if the Receiver Stop Enable
(RCSR[STOPE]) bit is clear, the receiver is disabled after completing the current receive
frame. Entry into Stop mode is prevented–not acknowledged–while waiting for the
transmitter and receiver to be disabled at the end of the current frame.
3.9.6.3.2 Low-leakage modes
When entering low-leakage modes, the Stop Enable (TCSR[STOPE] and
RCSR[STOPE]) bits are ignored and the SAI is disabled after completing the current
transmit and receive Frames. Entry into stop mode is prevented (not acknowledged)
while waiting for the transmitter and receiver to be disabled at the end of the current
frame.
