Break processing
1. Whether a framing error or parity error has
occurred in the receive data read from
SCFRDR2 can be ascertained from the FER
and PER bits in SCSSR2.
2. When a break signal is received, receive data
is not transferred to SCFRDR2 while the BRK
flag is set. However, note that the last data in
SCFRDR2 is H'00 and the break data in which
a framing error occurred is stored.
No
DR = 1?
Yes
Read receive data in SCFRDR2
Clear DR, ER, BRK flags in
SCSSR2 to 0
