System Overview
1.12.3 BMC Private I
The two private I
discrete temperature sensors, voltage sensors, an RTC, and an optional FRU EEPROM.
There are also routing resistors on the board that allow connection of these buses to the
Glue CPLD as a BOM option. The I

Programmable Logic

Two Programmable Logic Device (CPLD) are provided for various functions such as power
up control, CPU interface multiplexing, SMBus routing, and additional glue logic functions
needed on the card.
