9.3.1.6 Destructive Event Alternate Request Register (RGM_DEAR)
This register defines an alternate request to be generated when a reset on a destructive event has been
disabled. The alternate request can be either a SAFE mode request to MC_ME or an interrupt request to
the system.
AR_CHKSTOP Alternate Request for checkstop reset
0 Generate a SAFE mode request on a checkstop reset event if the reset is disabled
1 Generate an interrupt request on a checkstop reset event if the reset is disabled
AR_SOFT Alternate Request for software reset
0 Generate a SAFE mode request on a software reset event if the reset is disabled
1 Generate an interrupt request on a software reset event if the reset is disabled
AR_CORE Alternate Request for debug control core reset
0 Generate a SAFE mode request on a debug control core reset event if the reset is disabled
1 Generate an interrupt request on a debug control core reset event if the reset is disabled
AR_JTAG Alternate Request for JTAG initiated reset
0 Generate a SAFE mode request on a JTAG initiated reset event if the reset is disabled
1 Generate an interrupt request on a JTAG initiated reset event if the reset is disabled
