Destructive Event Status Register (RGM_DES)
This register contains the status of the last asserted destructive reset sources. It can be
accessed in read/write on either supervisor mode or test mode. Register bits are cleared on
write ‘1’.
F_CORE
Flag for core reset
0 No core reset event has occurred since either the last clear or the last destructive reset assertion
1 A core reset event has occurred
F_JTAG
Flag for JTAG initiated reset
0 No JTAG initiated reset event has occurred since either the last clear or the last destructive reset
assertion
1 A JTAG initiated reset event has occurred
