Retransmission when SCI is in Receive Mode: Figure 15.9 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.
4. When the received parity bit is checked and no error is found, reception is considered to have
5. When a normal frame is received, the pin maintains a three-state state when it transmits the

requested. Be sure to clear the PER bit before the next parity bit is sampled.
