10.2.6
EESR shows communication status information for both the E-DMAC and the EtherC. The
information in this register is reported in the form of interrupt sources. Individual bits are cleared
by writing 1 to them. Each bit can also be masked by means of the corresponding bit in the
EtherC/E-DMAC status interrupt permission register.
Bits 31 to 25—Reserved: These bits should only be written with 0.
Bit 24—Receive Frame Counter Overflow (RFCOF): Indicates that the receive FIFO frame
counter has overflowed.
