14.2.3

SCI Control Register 2 (SCIC2)

This register can be read or written at any time.

WAKE

Receiver Wakeup Method Select — Refer to Section 14.3.3.2, “Receiver Wakeup Operation” for more

information.

0 Idle-line wakeup.

1 Address-mark wakeup.

ILT

Idle Line Type Select — Setting this bit to 1 ensures that the stop bit and logic 1 bits at the end of a character

do not count toward the 10 or 11 bit times of logic high level needed by the idle line detection logic. Refer to

Section 14.3.3.2.1, “Idle-Line Wakeup” for more information.

0 Idle character bit count starts after start bit.

1 Idle character bit count starts after stop bit.

Parity Enable — Enables hardware parity generation and checking. When parity is enabled, the most significant

bit (MSB) of the data character (eighth or ninth data bit) is treated as the parity bit.

0 No hardware parity generation or checking.

1 Parity enabled.

Parity Type — Provided parity is enabled (PE = 1), this bit selects even or odd parity. Odd parity means the total

number of 1s in the data character, including the parity bit, is odd. Even parity means the total number of 1s in

the data character, including the parity bit, is even.

0 Even parity.

1 Odd parity.
