•
When the last bit of transmit data is transmitted
while the TENDSTS bit in SSCR2 is cleared to 0
and the TDRE bit is set to 1
After the last bit of transmit data is transmitted while
the TENDSTS bit in SSCR2 is set to 1 and the
TDRE bit is set to 1
When writing 0 after reading TEND = 1
When writing data to SSTDR
When the TE bit in SSER is 0
When data is transferred from SSTDR to SSTRSR
and SSTDR is ready to be written to.
When writing 0 after reading TDRE = 1
When writing data to SSTDR with TE = 1
When the DTC is activated by an SSTXI interrupt
and transmit data is written to SSTDR while the
DISEL bit in MRB of the DTC is 0
