Memory Map and Registers
15.4.1 Interrupt Mask Register High (INTC_IMRH)
INTC_IMRH, along with INTC_IMRL, provides a bit map for each interrupt to allow the
request to be disabled (masked) (1 = disable the request, 0 = enable the request). The
IMR is cleared by reset, enabling all interrupt requests to preserve compatibility with
earlier V1 ColdFire devices. The IMR can be read and written directly, or individual
mask flags can be set or cleared by accessing set/clear interrupt mask registers
(INTC_SIMR, INTC_CIMR).
