6.6.1 Conventions for Documenting Block Commands

According to the SMBus specification, block commands are transmitted across the PMBus interface in ascending order. The description below shows the convention this document follows for documenting block commands.

This document follows the convention for byte ordering of block commands:

When block values are listed as register map tables, they are listed in byte order from top to bottom starting with Byte N and ending with Byte 0.

Byte 0 (first byte sent) corresponds to bits 7:0.
Byte 1 (second byte sent) corresponds to bits 15:8.
Byte 2 (third byte sent) corresponds to bits 23:16.
… and so on

When block values are listed as text in hexadecimal, they are listed in byte order, from left to right, starting with Byte 0 and ending with Byte N with a space between each byte of the value. In block 54 49 54 6D 24 41h, the byte order is:

Byte 0, bits 7:0, = 54h
Byte 1, bits 15:8, = 49h
Byte 2, bits 23:16, = 6Dh
Byte 3, bits 31:24, = 24h
Byte 4, bits 39:32, = 41h
