TXIE

RXIE

ERRIE

WKIE

Reserved

Bit 7 TXIE: Tx buffer empty interrupt enable

0: TXE interrupt masked

1: TXE interrupt not masked. This allows an interrupt request to be generated when the TXE flag is

set.

Bit 6 RXIE: RX buffer not empty interrupt enable

0: RXNE interrupt masked

1: RXNE interrupt not masked. This allows an interrupt request to be generated when the RXNE flag

is set.

Bit 5 ERRIE: Error interrupt enable

0: Error interrupt is masked

1: Error interrupt is enabled. This allows an interrupt request to be generated when an error

condition occurs (CRCERR, OVR, MODF)

Bit 4 WKIE: Wakeup interrupt enable

0: Wakeup interrupt masked

1: Wakeup interrupt enabled. This allows an interrupt request to be generated when the WKUP flag

is set.

Bits 3:0 Reserved
