SCSR contains flags that show SCI operating conditions. These flags are cleared ei-
ther by SCI hardware or by a read/write sequence. The sequence consists of reading
SCSR, then reading or writing SCDR.
If an internal SCI signal for setting a status bit comes after reading the asserted status
bits, but before writing or reading SCDR, the newly set status bit is not cleared. SCSR
must be read again with the bit set and SCDR must be read or written before the status
bit is cleared.
A long-word read can consecutively access both SCSR and SCDR. This action clears
receive status flag bits that were set at the time of the read, but does not clear TDRE
or TC flags. Reading either byte of SCSR causes all 16 bits to be accessed, and any
status bit already set in either byte is cleared on a subsequent read or write of SCDR.
0 = SCI transmitter disabled (TXD pin can be used as I/O).
1 = SCI transmitter enabled (TXD pin dedicated to SCI transmitter).
0 = SCI receiver disabled.
1 = SCI receiver enabled.
0 = Normal receiver operation (received data recognized).
1 = Wake-up mode enabled (received data ignored until receiver is awakened).
0 = Normal operation
1 = Break frame(s) transmitted after completion of the current frame.
0 = Transmit data register still contains data to be sent to the transmit serial shifter.
1 = A new character can now be written to the transmit data register.
0 = SCI transmitter is busy.
1 = SCI transmitter is idle.
