14.3.7
SSR is a register containing status flags of the SCI and multiprocessor bits for transfer. TDRE,
RDRF, ORER, PER, and FER can only be cleared. Some bits in SSR have different functions in
normal mode and smart card interface mode.
• Bit Functions in Normal Serial Communication Interface Mode (when SMIF in SCMR = 0)

The RDRF flag is not affected and retains its
previous value when the RE bit in SCR is cleared to
0.
When the TE bit in SCR is 0
When data is transferred from TDR to TSR and
TDR is ready for data write
When 0 is written to TDRE after reading TDRE =
1
When a TXI interrupt request is issued allowing
DTC to write data to TDR
When serial reception ends normally and
receive data is transferred from RSR to RDR
= 1
When an RXI interrupt request is issued allowing
DTC to read data from RDR
When 0 is written to RDRF after reading RDRF
