Shelf Management Controller

The ShMC part is derived from Emerson's IPMC building block and consists of two coupled
microcontrollers:
IPMC Master Controller (IMC) based on an ATmega2560
IPMC Slave Controller (ISC), based on an ATmega168
8.3.1

IPMB0 Interface

IPMB0-A is connected to the I
of the ShMC. Both microcontrollers have their own I
transmission and reception independently, including bus error handling and bus arbitration.
Received messages sent from both the IMC and the ISC channels are collected by the IMC. The
IMC dispatches messages which have to be sent either to its own I
transmission.
