Bit 0 = PIE Parity interrupt enable.

This bit enables the interrupt capability of the hardware parity control when a parity

error is detected (PE bit set). It is set and cleared by software.

0: Parity error interrupt disabled

1: Parity error interrupt enabled

Control register 2 (SCICR2)

Reset value: 0000 0000 (00h)

Bit 7 = TIE Transmitter interrupt enable.

This bit is set and cleared by software.

0: Interrupt is inhibited

1: An SCI interrupt is generated whenever TDRE = 1 in the SCISR register

Bit 6 = TCIE Transmission complete interrupt enable

This bit is set and cleared by software.

0: Interrupt is inhibited

1: An SCI interrupt is generated whenever TC = 1 in the SCISR register

Bit 5 = RIE Receiver interrupt enable.

This bit is set and cleared by software.

0: Interrupt is inhibited

1: An SCI interrupt is generated whenever OR = 1 or RDRF = 1 in the SCISR register

Bit 4 = ILIE Idle line interrupt enable.

This bit is set and cleared by software.

0: Interrupt is inhibited

1: An SCI interrupt is generated whenever IDLE = 1 in the SCISR register.

Bit 3 = TE Transmitter enable.

This bit enables the transmitter. It is set and cleared by software.

0: Transmitter is disabled

1: Transmitter is enabled

Note:

During transmission, a “0” pulse on the TE bit (“0” followed by “1”) sends a preamble (idle

line) after the current word.

When TE is set there is a 1 bit-time delay before the transmission starts.

Bit 2 = RE Receiver enable.

This bit enables the receiver. It is set and cleared by software.

0: Receiver is disabled

1: Receiver is enabled and begins searching for a start bit
