Vender[7:0] - 0xffff
Vender [7:0] This code depends on
battery data format.
And the following name should be
described in the ASL with the same
character code.
In the future, these codes will be
added.
0: “MoliEnergy”
1: “Panasonic”
2: (SANYO does not agree the vender
name display)
3: “TBCL” (Toshiba)
4: “Sony”
*1: The register type is word.
*3: This register is not cleared if the system is in S4-S5 state.
R(/W): This is the read only register, but the written data will be able to read back till PMU updates the data
periodically, or PMU detects the status change.
