A.3.1.20 Maximum CCOB Latency
The maximum time a CCOB command has to wait to be actioned due to an EEE clean up is given where
BWN = 1 if a brownout has occured otherwise BWN = 0. BWN = 1 only for the first ENEEE after reset.
A.3.1.21 Disable EEE (FCMD=0x14)
Maximum time to disable EPROM emulation is given by
A.3.1.22 EEE Query (FCMD=0x15)
Maximum time for the EEE query command is given by
A.3.1.23 Partition D-Flash (FCMD=0x20)
The maximum time for partitioning the D-flash (ERPART=16, DFPART=0) is given by
