PRODUCTION DATA
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.
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 62h, the byte order is:
47 | 46 | 45 | 44 | 43 | 42 | 41 | 40 |
RW | RW | RW | RW | RW | RW | RW | RW |
Byte N | |||||||
39 | 38 | 37 | 36 | 35 | 34 | 33 | 32 |
RW | RW | RW | RW | RW | RW | RW | RW |
Byte … | |||||||
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 |
RW | RW | RW | RW | RW | RW | RW | RW |
Byte 3 | |||||||
23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 |
RW | RW | RW | RW | RW | RW | RW | RW |
Byte 2 | |||||||
15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 |
RW | RW | RW | RW | RW | RW | RW | RW |
Byte 1 | |||||||
7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
RW | RW | RW | RW | RW | RW | RW | RW |
Byte 0 |
