This subsection contains a description of the interrupt controller module
register set.
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.
AE — Autovector Enable Bit
FVE — Fast Vector Enable Bit
The read/write AE bit enables fast and normal autovectored interrupt
requests. Reset sets AE.
The read/write FVE bit enables fast vectored interrupt requests to
have vector numbers separate from normal vectored interrupt
requests. Reset clears FVE.

For More Information On This Product,
1 = Autovectored interrupt requests
0 = Vectored interrupt requests
1 = Unique vector numbers for fast vectored interrupt requests
0 = Same vector number for fast and normal vectored interrupt
