10.2.8 Transmit/Receive Status Copy Enable Register (TRSCER)
TRSCER specifies whether or not multicast address frame receive status information reported by
bit 7 in the EtherC/E-DMAC status register (EESR) is to be indicated in the corresponding
descriptor. Bit 7 in TRSCER corresponds to bit 7 of EESR. When bit 7 is set to 0, the receive
status (bit 7 of EESR) is indicated in the RFE bit of the receive descriptor. When the bit is set to 1,
the occurrence of the corresponding source is not indicated in the descriptor. After the chip is
reset, the bit is cleared to 0.

Description
Enables the RMAF bit status to be indicated in the RFS7 bit in the receive
descriptor.
Disables occurrence of corresponding source to be indicated in the RFS7 bit in
the receive descriptor.
Bits 6 to 0âReserved: These bits are always read as 0. The write value should always be 0.
