Notes: 1. This table shows the initial state immediate 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 be accepted first, with the result
that the TDRE and TEND flags are cleared. Note that the TEI interrupt will not be accepted in this
case.
2. The DMAC is not supported in the H8S/2321.
