CR15/CR18 VID Control
CR16 Entry/Disable VID Output
Note. Programming VID for output and using VID pins as GPIO are different. Programming VID output
will activate VID translation, but GPIO will not.
Writing VID should be separated into 2 steps at the first time after VID Entry is enabled. One for set
EN_VIDOUT, the other for set the wanted VID. These actions are used to inform VID Limit Generator
generate new VCORE Limits for written VID. If writing EN_VIDOUT/VIDOUT in the same SMBus
transaction, VID will be output to port but will not update internal Vcore Limits.
VID on the fly flag is only used in VRM10 mode. User should not assume its value under VRM9 value.

ENTRY_ST
7~0 Pattern
VIDIN latches external pin value, and will not affect by VIDOUTDATA.
Set to enable VID output.
VID on the fly. (Read only) Use to indicate VID have been changed in last 1ms~2ms.
The desired VID to output to pin. (ENTRY OK must be 1 to write this register)
Read only. An one means entry pattern all successfully received, and programming
VID function is valid.
Read only. These 2 bits indicate how many patterns have been written into CR16.
Write 8-bit to input patterns for writing VID output privilege. Entrance:
5A(Entry_ST=1), 73(Entry_ST=2), B2(Entry_ST=3), E0(ENTRY_OK=1). Exit:
A5(Entry_ST=2), 4C(Entry_ST=1), D9(Entry_ST=0), 8A(ENTRY_OK=0). The
pattern must be sequentially input without other writes interrupt, otherwise, the
current input sequence is considered as in-effective.
