FE — Receiver Framing Error Flag
This clearable, read-only flag is set when there is a logic 0 where a
stop bit should be in the character shifted into the receive shift
register. If the received word causes both a framing error and an
overrun error, the OR bit is set and the FE bit is not set. Clear the FE
bit by reading the SCSR, and then reading the SCDR. Reset clears
the FE bit.
1 = Framing error
0 = No framing error
9.6.5 Baud Rate Register
The baud rate register (BAUD) selects the baud rate for both the receiver
and the transmitter.
SCP1 and SCP0 — SCI Prescaler Select Bits
These read/write bits control prescaling of the baud rate generator
clock, as shown in Table 9-1. Resets clear both SCP1 and SCP0.
