Table 6-11. Interrupt Flag Register (IFR) — CPU Register Field Descriptions
Bits Field Value Description
15 RTOSINT Real-time operating system flag. RTOSINT is the flag for RTOS interrupts.
0 No RTOS interrupt is pending
1 At least one RTOS interrupt is pending. Write a 0 to this bit to clear it to 0 and clear the interrupt
request
14 DLOGINT Data logging interrupt fag. DLOGINT is the flag for data logging interrupts.
0 No DLOGINT is pending
1 At least one DLOGINT interrupt is pending. Write a 0 to this bit to clear it to 0 and clear the interrupt
request
13 INT14 Interrupt 14 flag. INT14 is the flag for interrupts connected to CPU interrupt level INT14.
0 No INT14 interrupt is pending
1 At least one INT14 interrupt is pending. Write a 0 to this bit to clear it to 0 and clear the interrupt
request
12 INT13 Interrupt 13 flag. INT13 is the flag for interrupts connected to CPU interrupt level INT13I.
0 No INT13 interrupt is pending
1 At least one INT13 interrupt is pending. Write a 0 to this bit to clear it to 0 and clear the interrupt
request
11 INT12 Interrupt 12 flag. INT12 is the flag for interrupts connected to CPU interrupt level INT12.
0 No INT12 interrupt is pending
1 At least one INT12 interrupt is pending. Write a 0 to this bit to clear it to 0 and clear the interrupt
request
10 INT11 Interrupt 11 flag. INT11 is the flag for interrupts connected to CPU interrupt level INT11.
0 No INT11 interrupt is pending
1 At least one INT11 interrupt is pending. Write a 0 to this bit to clear it to 0 and clear the interrupt
request
9 INT10 Interrupt 10 flag. INT10 is the flag for interrupts connected to CPU interrupt level INT10.
0 No INT10 interrupt is pending
1 At least one INT6 interrupt is pending. Write a 0 to this bit to clear it to 0 and clear the interrupt
request
8 INT9 Interrupt 9 flag. INT9 is the flag for interrupts connected to CPU interrupt level INT6.
0 No INT9 interrupt is pending
1 At least one INT9 interrupt is pending. Write a 0 to this bit to clear it to 0 and clear the interrupt
request
7 INT8 Interrupt 8 flag. INT8 is the flag for interrupts connected to CPU interrupt level INT6.
0 No INT8 interrupt is pending
1 At least one INT8 interrupt is pending. Write a 0 to this bit to clear it to 0 and clear the interrupt
request
6 INT7 Interrupt 7 flag. INT7 is the flag for interrupts connected to CPU interrupt level INT7.
0 No INT7 interrupt is pending
1 At least one INT7 interrupt is pending. Write a 0 to this bit to clear it to 0 and clear the interrupt
request
