explains the bit functions of the IP register.
explains the bit functions of the EXIF register.
ET1 - Enable Timer 1 interrupt. ET1 = 0 disables Timer 1 interrupt
(TF1). ET1 = 1 enables interrupts generated by the TF1 flag.
EX1 - Enable external interrupt 1. EX1 = 0 disables external interrupt 1
(INT1_N). EX1 = 1 enables interrupts generated by the INT1_N pin.
ET0 - Enable Timer 0 interrupt. ET0 = 0 disables Timer 0 interrupt
(TF0). ET0 = 1 enables interrupts generated by the TF0 flag.
EX0 - Enable external interrupt 0. EX0 = 0 disables external interrupt 0
(INT0_N). EX0 = 1 enables interrupts generated by the INT0_N pin.
Function
Reserved. Read as 1.
Reserved. Read as 0.
PT2 - Timer 2 interrupt priority control. PT2 = 0 sets Timer 2 interrupt
(TF2) to low priority. PT2 = 1 sets Timer 2 interrupt to high priority.
PS - Serial Port interrupt priority control. PS = 0 sets Serial Port interrupt
(TI or RI) to low priority. PS = 1 sets Serial Port interrupt to high
priority.
PT1 - Timer 1 interrupt priority control. PT1 = 0 sets Timer 1 interrupt
(TF1) to low priority. PT1 = 1 sets Timer 1 interrupt to high priority.
PX1 - External interrupt 1 priority control. PX1 = 0 sets external
interrupt 1 (INT1_N) to low priority. PT1 = 1 sets external interrupt 1 to
high priority.
PT0 - Timer 0 interrupt priority control. PT0 = 0 sets Timer 0 interrupt
(TF0) to low priority. PT0 = 1 sets Timer 0 interrupt to high priority.
PX0 - External interrupt 0 priority control. PX0 = 0 sets external
interrupt 0 (INT0_N) to low priority. PT0 = 1 sets external interrupt 0 to
high priority.
Function
IE5 - Interrupt 5 flag. IE5 = 1 indicates that a rising edge was detected on
the RADIO.DR2 signal.(see ch. 5.1.RADIO) IE5 must be cleared by
software. Setting IE5 in software generates an interrupt, if enabled.
IE4 - Interrupt 4 flag. IE4 = 1 indicates that a rising edge was detected on
the RADIO.DR1 signal.(see ch. 5.1.RADIO) IE4 must be cleared by
software. Setting IE4 in software generates an interrupt, if enabled.
IE3 - Interrupt 3 flag. IE3 = 1 indicates that the internal SPI module has
sent or received 8 bits, and is ready for a new command. IE3 must be
cleared by software. Setting IE3 in software generates an interrupt, if
enabled.
