The upper and lower byte of this register (index 7Ch), in conjunction with the upper byte of index
register 7Eh, make up the vendor identification code for the W83971D. The Vendor ID Code (in
ASCII format) is equal to WEC (Winbond Elec. Inc.,), where:
F[7:0] Upper Byte (Index 7Ch) D[15:8] = W
S[7:0] Lower Byte (Index 7Ch) D[7:0] = E
T[15:8] Upper Byte (Index 7Eh) D[15:8] = C
The upper byte of this register is used in conjunction with index register 7Ch to make up the Vendor
ID code for the W83971D. The lower byte identifies the revision code of the W83971D.
T[15:8] See description in Vendor Identification Register.
REV[7:0] Revision ID "01" as Revision Number.
