TPS53676 supports 3 data formats according to the PMBus specification. The data format for each command is listed along with its address and supported values.

• ULINEAR16 format uses a 16-bit unsigned integer. The default LSB size is 2^-10 = 0.97656 mV
• SLINEAR16 format uses a 16-bit number representing a decimal. This number has two fields: the 5 MSB bits form an two's complement exponent, referred to as N, and the 11 LSB bits form a two's complement mantissa, referred to as M. The decimal number is represented as D = M × 2^N
• Unsigned binary format uses direct bit maps with each command being subdivided into multiple fields that can have different meaning. Refer to the register maps in the Technical Reference Manual for these commands.

TPS53676 accepts writes to SLINEAR11 format commands with any desired exponent value. TI recommends using the default exponent listed for each command for writes to ensure consistent NVM store and restore behavior.

Telemetry commands in the SLINEAR11 format return data with variable exponent values according to the absolute value of the retured value. As a rule TPS53676 returns data in the SLINEAR11 format with the smallest possible exponent, to provide the highest possible command resolution. As a result the host must be able to support decoding of the SLINEAR11 format with any exponent value.
