If this bit is set to 1 and watchdog timeout event occurs, RSTOUT# output
is enabled.
If private keys are entered correctly, this bit will be set to 1.
If this bit is set to 1 and “MANUAL_MODE” is 0, VID on the fly is enabled
and VID_OUT will be new VID_OUT. If this bit is set to 0, VID_OUT will be
VID_IN. This bit is also cleared by slotocc and reset signal of watchdog
timeout. (Protected by serial key)
If this bit is set to 1 and “OTF_EN” is 1, VID_OUT will be “VID_MANUAL”
in register index 0x04. (Protected by serial key)
This bit is protected by serial key.

4~7: Reserved
Private key value (0x32 0x5d 0x42 0xac)
VID_IN reading from CPU. If GP2_SEL[1] is 0, the VID_IN is current VID
of CPU. If GP2_SEL[1] is set from 0 to 1, the VID of CPU is latched at this
time.
If “MANUAL_MODE” is set to 1 and “OTF_EN” is set to 0, VID_OUT will
be VID_MANUAL. (Protected by serial key)
If “CURRENT_SEC” in loading gauge register (Index 18h) is 0,
VID_OFFSET0 is selected as the offset of VID. VID_OFFSET0[7] is a sign
bit. (Protected by serial key)
If “CURRENT_SEC” in loading gauge register (Index 18h) is 1,
VID_OFFSET1 is selected as the offset of VID. VID_OFFSET1[7] is a sign
bit. (Protected by serial key)
