Figure 32-6. Functional Event Alternate Request Register (RGM_FEAR)
This register defines an alternate request to be generated when a reset on a functional event has been
disabled. The alternate request can be either a SAFE mode request to MC_ME or an interrupt request to
the system. It can be accessed in read/write in either supervisor mode or test mode. It can be accessed in
read only in user mode.
