Description
Remap control register.
RSTSTA status MMR.
RSTCLR MMR for clearing RSTSTA register.
0x76 should be written to this register before writing to RSTCFG.
This register allows the DAC and GPIO outputs to retain state after a
watchdog or software reset.
0xB1 should be written to this register after writing to RSTCFG.
Description
Active IRQ source.
Current state of all IRQ sources (enabled and disabled).
Enabled IRQ sources.
MMR to disable IRQ sources.
Software interrupt configuration MMR.
Base address of all vectors. Points to start of a 64-byte memory block
which can contain up to 32 pointers to separate subroutine handlers.
This register contains the subroutine address for the currently active IRQ
source.
This register contains the interrupt priority setting for Interrupt Source 1
to Interrupt Source 7. An interrupt can have a priority setting of 0 to 7.
This register contains the interrupt priority setting for Interrupt Source 8
to Interrupt Source 15.
This register contains the interrupt priority setting for Interrupt Source 16 to
Interrupt Source 21.
Reserved.
Used to enable IRQ and FIQ interrupt nesting.
This register configures the external interrupt sources as rising edge,
falling edge, or level triggered.
Used to clear an edge level triggered interrupt source.
This register indicates the priority level of an interrupt that has just
caused an interrupt exception.
Active FIQ source.
Current state of all FIQ sources (enabled and disabled).
Enabled FIQ sources.
MMR to disable FIQ sources.
FIQ interrupt vector.
This register indicates the priority level of an FIQ that has just caused an
FIQ exception.
