Bit

7 to 0
Description
Command with which the high voltage data, HVDAT[7:0], is associated. These bits are read-only and should be written as 0s.
0x00 = read back the high voltage register, HVCFG, into HVDAT.
0x02 = read back the high voltage status register, HVSTA, into HVDAT.
0x08 = write the value in HVDAT to the high voltage register, HVCFG.
High voltage data to read/write.
HVDAT
0xFFFF080C
Updated by kernel
Read/write
HVDAT is a 12-bit register that is used to hold data to be written indirectly to, and read indirectly from, the HVDAT,
HVSTA, HVCFG high voltage interface registers.
HVCON
0xFFFF0804
Updated by kernel
Read/write
This 8-bit register acts as a command byte interpreter for the high voltage control interface. Bytes written to this
register are interpreted as read or write commands to a set of two indirect registers related to the high voltage
circuits. The HVDAT register is used to store data to be written to, or read back from, the indirect registers.
Description
Reserved.
Transmit command to high voltage die status.
1 = command completed successfully.
0 = command failed.
Read command from high voltage die status.
1 = command completed successfully.
0 = command failed.
Bit 0 (read-only) busy bit. When user code reads this register, Bit 0 should be interpreted as the busy signal for the high
voltage interface. This bit can be used to determine if a read request has completed. High voltage (read/write) com-
mands as described in this table should not be written to HVCON unless busy = 0.
Busy = 1, high voltage interface is busy and has not completed the previous command written to HVCON. Bit 1 and Bit 2
are not valid.
Busy = 0, high voltage interface is not busy and has completed the command written to HVCON. Bit 1 and Bit 2 are valid.
Description
Command byte. Interpreted as
0x00 = read back high voltage register, HVCFG, into HVDAT.
0x02 = read back high voltage status register, HVSTA, into HVDAT.
0x08 = write the value in HVDAT to the high voltage register, HVCFG.
Other = reserved.
