PT — Parity Type
0 = Even parity
1 = Odd parity
When parity is enabled, PT determines whether parity is even or odd for both the receiver and the trans-
mitter.
PE — Parity Enable
0 = SCI parity disabled
1 = SCI parity enabled
PE determines whether parity is enabled or disabled for both the receiver and the transmitter. If the re-
ceived parity bit is not correct, the SCI sets the PF error flag in SCSR.
When PE is set, the most significant bit (MSB) of the data field is used for the parity function, which re-
sults in either seven or eight bits of user data, depending on the condition of M bit. The following table
lists the available choices.
M — Mode Select
0 = SCI frame: one start bit, eight data bits, one stop bit (ten bits total)
1 = SCI frame: one start bit, nine data bits, one stop bit (11 bits total)
WAKE — Wakeup by Address Mark
0 = SCI receiver awakened by idle-line detection
1 = SCI receiver awakened by address mark (last bit set)
TIE — Transmit Interrupt Enable
0 = SCI TDRE interrupts inhibited
1 = SCI TDRE interrupts enabled
TCIE — Transmit Complete Interrupt Enable
0 = SCI TC interrupts inhibited
1 = SCI TC interrupts enabled
RIE — Receiver Interrupt Enable
0 = SCI RDRF interrupts inhibited
1 = SCI RDRF interrupts enabled
ILIE — Idle-Line Interrupt Enable
0 = SCI IDLE interrupts inhibited
1 = SCI IDLE interrupts enabled
TE — Transmitter Enable
0 = SCI transmitter disabled (TXD pin may be used for general-purpose I/O)
1 = SCI transmitter enabled (TXD pin dedicated to SCI transmitter)
The transmitter retains control of the TXD pin until completion of any character transfer in progress
when TE is cleared.
RE — Receiver Enable
0 = SCI receiver disabled (status bits inhibited, RXD pin may be used for general-purpose I/O))
1 = SCI receiver enabled (RXD pin dedicated to SCI)
