Fast Ethernet Controller (FEC)
The MIBC is a read/write register controlling and observing the state of the MIB block. User software
accesses this register if there is a need to disable the MIB block operation. For example, to clear all MIB
counters in RAM:
The MIB_DIS bit is reset to 1. See
17.4.10 Receive Control Register (RCR)
RCR controls the operational mode of the receive block and must be written only when ECR[ETHER_EN]
is cleared (initialization time).
