USART INTSTAT addressOffset = 0x024

The read-only INTSTAT register provides a view of those interrupt flags that are currently enabled. This can simplify software handling of interrupts. See USART registerName = STAT addressOffset = 0x008 for detailed descriptions of the interrupt flags.

Table 1. USART registerName = INTSTAT addressOffset = 0x024
Bit Symbol Description Reset Value
0 RXRDY Receiver Ready flag. 0
1 - Reserved. Read value is undefined, only zero should be written. NA
2 TXRDY Transmitter Ready flag. 1
4:3 - Reserved. Read value is undefined, only zero should be written. NA
5 DELTACTS This bit is set when a change in the state of the CTS input is detected. 0
6 TXDISINT Transmitter Disabled Interrupt flag. 0
7 - Reserved. Read value is undefined, only zero should be written. NA
8 OVERRUNINT Overrun Error interrupt flag. 0
10:9 - Reserved. Read value is undefined, only zero should be written. NA
11 DELTARXBRK This bit is set when a change in the state of receiver break detection occurs. 0
12 START This bit is set when a start is detected on the receiver input. 0
13 FRAMERRINT Framing Error interrupt flag. 0
14 PARITYERRINT Parity Error interrupt flag. 0
15 RXNOISEINT Received Noise interrupt flag. 0
31:16 - Reserved. Read value is undefined, only zero should be written. NA
