TDRE — Transmit Data Register Empty Flag
TC — Transmit Complete Flag
Read:
Write:
The TDRE flag is set when the transmit shift register receives a word
from the SCI Data Register. It signals that the SCIDRH and SCIDRL
are empty and can receive new data to transmit. If the TIE bit in the
SCICR2 is also set, TDRE generates an interrupt request. Clear
TDRE by reading SCISR1 and then writing to SCIDRL. Reset sets
TDRE.
The TC flag is set when TDRE = 1 and no data, preamble, or break
frame is being transmitted. It signals that no transmission is in
progress. If the TCIE bit is set in SCICR2, TC generates an interrupt
request. When TC is set, the TXD pin is idle (logic 1). TC is cleared
automatically when a data, preamble, or break frame is queued. Clear
TC by reading SCISR1 with TC set and then writing to SCIDRL. TC
cannot be cleared while a transmission is in progress. Reset sets TC.
