Status Register:
TIC Input Select Register:
TIC Register:
enable each interrupt source
0 : disable interrupt (default)
1 : enable interrupt
interrupt sources will trigger nIRQ or nFIQ
0 : activate nIRQ output (default)
1 : activate nFIQ output
current interrupt request status (read-only)
0 : no interrupt request
1 : interrupt pending (masked interrupt is always "0")
Chip test purpose only.
Should be "0" during normal operation.
0 : normal function
1 : select TIC Register as interrupt sources
Chip test purpose only.
Used as interrupt sources in TIC mode.
Should be "0" during normal operation.
