Parity Enable

This bit enables the parity function. When enabled, the function replaces the most significant bit

of the data character with a parity bit.

Parity function disabled

Parity function enabled

Parity Type

This bit determines if the SCI generates and checks for even or odd parity of the data bits.

Even Parity

Odd parity

TEIE

Transmitter Empty Interrupt Enable

This bit enables Transmit Data Register Empty (TDRE) flag to generate interrupt requests.

TDRE interrupt requests disabled

TDRE interrupt requests enabled

TIIE

Transmitter Idle Interrupt Enable

This bit enables the Transmitter Idle (TIDLE) flag to generate interrupt requests.

TIDLE interrupt requests disabled

TIDLE interrupt requests enabled

RFIE

Receiver Full Interrupt Enable

This bit enables the Receive Data Register Full (RDRF) flag, or the Overrun (OR) flag to generate

interrupt requests.

RDRF and OR interrupt requests disabled

RDRF and OR interrupt requests enabled
