High Voltage Data Register
Name: HVDAT
Address: 0xFFFF080C
Default Value: Updated by kernel
Access: Read/write
Function: HVDAT is a 12-bit register that is used to hold data to be written indirectly to, and read indirectly from, the following
high voltage interface registers.
Table 73. HVDAT MMR Bit Designations
Bit Description
11 to 8
Command with which High Voltage Data HVDAT[7:0] is associated. These bits are read only and should be written as
zeros.
0x00 = read back High Voltage Register HVCFG0 into HVDAT.
0x01 = read back High Voltage Register HVCFG1 into HVDAT.
0x02 = read back High Voltage Status Register HVSTA into HVDAT.
0x03 = read back High Voltage Status Register HVMON into HVDAT.
0x08 = write the value in HVDAT to the High Voltage Register HVCFG0.
0x09 = write the value in HVDAT to the High Voltage Register HVCFG1.
7 to 0 High Voltage Data to Read/Write.
