Description
Always reads as 0000.
Threshold for the IOUT measurement through the sense resistor, expressed in ADC
codes. This value can be either an undercurrent or an overcurrent, depending on the
state of the IOUT_WARN2_SELECT bit that is set using the DEVICE_CONFIG command.
Description
Hot swap output is disabled.
Default. Hot swap output is enabled.
Always reads as 0000000.
Description
Always reads as 1. Packet error checking (PEC) is supported.
Always reads as 01. Maximum supported bus speed is 400 kHz.
Always reads as 1. Device supports SMBAlert and alert response address (ARA).
Always reads as 0000.
Description
