Retransmission by the SCI in Receive Mode: Figure 14.9 shows the retransmission operation in
the SCI receive mode.
1. When the received parity bit is checked and an error is found, the PER bit in SCSSR is
2. The RDRF bit in SCSSR is not set in the frame that caused the error.
3. When the received parity bit is checked and no error is found, the PER bit in SCSSR is not set.
