11.1.2.3 Receive Data Section Status Byte (ASYNC/BISYNC Modes)
In ASYNC/BISYNC protocol mode additionally to every data byte, an attached status
byte can be stored (CCR2:RFDF=’1’).
The data character and status character format is determined as follows:
Figure 79
Note: The ’Frame Error’ (FE) status bit is only valid in ASYNC protocol mode.
RFDF=’0’
data byte:
(no parity bit stored)
P : Parity bit stored in data byte, can be disabled via bit ’DPS’
PE: Parity Error
FE: Frame Error
P: Parity bit stored in second data byte (= status byte)
