Note: * This table shows the initial state immediately after a reset. Relative priorities among
A TEI interrupt is requested when the TEND flag is set to 1 while the TEIE bit is set to 1. The
TEND flag is cleared at the same time as the TDRE flag. Consequently, if a TEI interrupt and a
TXI interrupt are requested simultaneously, the TXI interrupt may have priority for acceptance,
with the result that the TDRE and TEND flags are cleared. Note that the TEI interrupt will not be
accepted in this case.
channels can be changed by means of the interrupt controller.
