7.7.2 Registers
This subsection contains a description of the interrupt controller module
registers.
7.7.2.1 Interrupt Control Register
The 16-bit interrupt control register (ICR) selects whether interrupt
requests are autovectored or vectored, and if vectored, whether fast
interrupts generate a different vector number than normal interrupts.
This register also controls the masking functions.
Address: 0x00c5_0000 and 0x00c5_0001

AE — Autovector Enable Bit
The read/write AE bit enables autovectored interrupt requests. Reset
sets AE.
1 = Autovectored interrupt requests
0 = Vectored interrupt requests
FVE — Fast Vector Enable Bit
The read/write FVE bit enables fast vectored interrupt requests to
have vector numbers separate from normal vectored interrupt
requests. Reset clears FVE.
1 = Unique vector numbers for fast vectored interrupt requests
0 = Same vector number for fast and normal vectored interrupt
requests
