Bit 5: TAIL MARK control (MRKON)
Bit 5 controls tail mark output after transfer of 8-bit or 16-bit data.
Bit 5
MRKON Description
0 TAIL MARK is not output (synchronous mode) (initial value)
1 TAIL MARK is output (SSB mode)
Bit 4: LATCH TAIL select (LTCH)
Bit 4 selects whether LATCH TAIL or HOLD TAIL is output as the tail mark when MRKON = 1
(i.e. in SSB mode).
