IMR[63:0] - Interrupt Mask Register (IMRH, IMRL)

The IMRH and IMRL registers are each 32 bits in size, and provide a bit map for each interrupt to allow

the request to be disabled or “masked” (1 = disable the request, 0 = enable the request). The IMR is set to

all ones by reset, disabling all interrupt requests. The IMR can be read and written directly, or individual

mask flags can be set or cleared by accesses through the SIMR (Set Interrupt Mask) or CIMR (Clear

Interrupt Mask) registers.

Each bit of the IMR[n] is associated with the corresponding bit of the IPR[n].

See Figure 14-3 and Table 14-8 for the IPR definition.
