IF[39:0] — Interrupt Force Field
This read/write field forces interrupt requests at the corresponding
source numbers. Reference Table 8-6 for interrupt source numbers
to determine which bit(s) to set in this register. IFRH and IFRL allow
software generation of interrupt requests for functional or debug
purposes. Writing 0 to an IF bit negates the interrupt request. Reset
clears the IF[39:0] field.
1 = Force interrupt request
0 = Interrupt source not forced
Address: 0x00c5_0008 through 0x00c5_000b
