USART INTENSET addressOffset = 0x00C

The INTENSET register is used to enable various USART interrupt sources. Enable bits in INTENSET are mapped in locations that correspond to the flags in the STAT register. The complete set of interrupt enables may be read from this register. Writing ones to implemented bits in this register causes those bits to be set. The INTENCLR register is used to clear bits in this register.

Bit Symbol Description Reset Value
0 RXRDYEN When 1, enables an interrupt when there is a received character available to be read from the RXDAT register. 0
1 - Reserved. Read value is undefined, only zero should be written. NA
2 TXRDYEN When 1, enables an interrupt when the TXDAT register is available to take another character to transmit. 0
4:3 - Reserved. Read value is undefined, only zero should be written. NA
5 DELTACTSEN When 1, enables an interrupt when there is a change in the state of the CTS input. 0
6 TXDISINTEN When 1, enables an interrupt when the transmitter is fully disabled as indicated by the TXDISINT flag in STAT. See description of the TXDISINT bit for details. 0
7 - Reserved. Read value is undefined, only zero should be written. NA
8 OVERRUNEN When 1, enables an interrupt when an overrun error occurred. 0
10:9 - Reserved. Read value is undefined, only zero should be written. NA
11 DELTARXBRKEN When 1, enables an interrupt when a change of state has occurred in the detection of a received break condition (break condition asserted or deasserted). 0
12 STARTEN When 1, enables an interrupt when a received start bit has been detected. 0
13 FRAMERREN When 1, enables an interrupt when a framing error has been detected. 0
14 PARITYERREN When 1, enables an interrupt when a parity error has been detected. 0
15 RXNOISEEN When 1, enables an interrupt when noise is detected. See description of the RXNOISEINT bit in USART registerName = STAT addressOffset = 0x008. 0
31:16 - Reserved. Read value is undefined, only zero should be written. NA
