* _{This register is reset if and only if one of thefollowing occurs:}
• Power up
• 1.2 V low-voltage detection (i.e. when the core voltage drops below the point at which the flip-flops can reliably retain
their value)
Figure 41-8. 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.
