Description
STIF – Sleep timer interrupt flag
0 Interrupt not pending
1 Interrupt pending
Must be written 0. Writing a 1 will always enable interrupt source.
P0IF – Port 0 interrupt flag
0 Interrupt not pending
1 Interrupt pending
T4IF – Timer 4 interrupt flag. Set to 1 when Timer 4 interrupt
occurs and cleared when CPU vectors to the interrupt service
routine.
0 Interrupt not pending
1 Interrupt pending
T3IF – Timer 3 interrupt flag. Set to 1 when Timer 3 interrupt
occurs and cleared when CPU vectors to the interrupt service
routine.
0 Interrupt not pending
1 Interrupt pending
T2IF – Timer 2 interrupt flag. Set to 1 when Timer 2 interrupt
occurs and cleared when CPU vectors to the interrupt service
routine.
0 Interrupt not pending
1 Interrupt pending
T1IF – Timer 1 interrupt flag. Set to 1 when Timer 1 interrupt
occurs and cleared when CPU vectors to the interrupt service
routine.
0 Interrupt not pending
1 Interrupt pending
DMAIF – DMA complete interrupt flag.
0 Interrupt not pending
1 Interrupt pending
