to enable interrupt requests, when a transmit error occurs and the ERS flag is set to 1, a
transmit/receive-error interrupt (ERI) is requested.
The timing of TEND flag setting depends on the GM bit in SMR. The timing is shown in figure
14.6.
If the TXI interrupt activates the DMAC, the number of bytes designated in the DMAC can be
transmitted automatically, including automatic retransmit.
For details, see Interrupt Operations and Data Transfer by DMAC in this section.
