Bit 7 = R8 Receive data bit 8
This bit is used to store the 9th bit of the received
word when M = 1.
Bit 6 = T8 Transmit data bit 8
This bit is used to store the 9th bit of the transmit-
ted word when M = 1.
Bit 5 = SCID Disabled for low power consumption
When this bit is set the SCI prescalers and outputs
are stopped and the end of the current byte trans-
fer in order to reduce power consumption.This bit
is set and cleared by software.
0: SCI enabled
1: SCI prescaler and outputs disabled
Bit 4 = M Word length
This bit determines the word length. It is set or
cleared by software.
0: 1 Start bit, 8 Data bits, 1 Stop bit
1: 1 Start bit, 9 Data bits, 1 Stop bit
Note: The M bit must not be modified during a data
transfer (both transmission and reception).

Bit 3 = WAKE Wake-Up method
This bit determines the SCI Wake-Up method, it is
set or cleared by software.
0: Idle Line
1: Address Mark
Note: If the LINE bit is set, the WAKE bit is deacti-
vated and replaced by the LHDM bit.
Bit 2 = PCE Parity control enable
This bit is set and cleared by software. It selects
the hardware parity control (generation and detec-
tion for byte parity, detection only for LIN parity).
0: Parity control disabled
1: Parity control enabled
Bit 1 = PS Parity selection
This bit selects the odd or even parity when the
parity generation/detection is enabled (PCE bit
set). It is set and cleared by software. The parity
will be selected after the current byte.
0: Even parity
1: Odd parity
Bit 0 = PIE Parity interrupt enable
This bit enables the interrupt capability of the hard-
ware parity control when a parity error is detected
(PE bit set). The parity error involved can be a byte
parity error (if bit PCE is set and bit LPE is reset) or
a LIN parity error (if bit PCE is set and bit LPE is
set).
0: Parity error interrupt disabled
1: Parity error interrupt enabled
