Lock bit for Catastrophic (LBC) — R/W. This bit may only be set to a 0 by a hardware reset.
Writing a 0 to this bit has no effect.
1 = Locks the Catastrophic programming interface including TSxTTP.bits[7:0].
0 = Catastrophic programming interface is unlocked
Reserved
Policy Lock-Down Bit — R/W. This bit may only be set to a 0 by a hardware reset. Writing a 0 to
this bit has no effect.
1 = Prevents writes to this register.
0 = This register can be programmed and modified.
NOTE: TSxCO.bit 7 and TSxLOCK.bit 2 must also be 1 when this bit is set to 1.
Catastrophic Power-Down Enable — R/W.
0 = Disable
1 = Enable. Power management logic unconditionally transitions to the S5 state when
