R is read, and W is write.
32 ZP is a 24- or 20-bit, signed or unsigned register that is transmitted as a 32-bit word with 8 or 12 MSBs, respectively, padded with 0s. 32 SE is a 24-bit, signed register
that is transmitted as a 32-bit word that is sign extended to 32 bits.
U indicates an unsigned register, and S indicates a signed register in twos complement format.
N/A is not applicable.

Bits
[23:0]
Default Value
0x000000
Description
When HPFDIS = 0x000000, all high-pass filters in voltage and current channels are enabled.
When the register is set to any nonzero value, all high-pass filters are disabled.
