IOUT_CAL_OFFSET is used to compensate for offset errors in the READ_IOUT command. Each PHASE in a stack can apply an independent IOUT_CAL_OFFSET value. The effective IOUT_CAL_OFFSET value for a stack is equal to the sum of the IOUT_CAL_OFFSET values from all devices in the stack.

Attempts to write (39h) IOUT_CAL_OFFSET to any value outside those specified as valid will be considered invalid/unsupported data and cause the TPSM8S6C24 to respond by flagging the appropriate status bits and notifying the host according to the PMBus 1.3.1 Part II specification section 10.9.3.

Command Resolution and NVM Store/Restore Behavior

The (39h) IOUT_CAL_OFFSET command is implemented using the TPSM8S6C24 internal telemetry system. As a result, the value of this command can be programmed with very high resolution using the linear format. However, the only provides limited NVM-backed options for this command. Following a power-cycle or NVM Store/Restore operation, the value will be restored to one of the supported values, according to the value present during the last NVM store operation. During operation, updates to this command with higher resolution, will be supported, and accepted as long as they fall between the minimum and maximum supported values given.

Phased Command Behavior

PHASE = 00h to 03h: Writes to (39h) IOUT_CAL_OFFSET modify the current sense offset for individual phases. Reads to (39h) IOUT_CAL_OFFSET return the configured current sense offset for individual phases.

PHASE = FFh: Writes to (39h) IOUT_CAL_OFFSET modify the total current sense offset for all individual phases. Individual phases will be assigned an IOUT_CAL_OFFSET value equal to the written value divided by the number of phases. Reads to (39h) IOUT_CAL_OFFSET return the configured current sense offset for PHASE = 00h times the number of phases.
