23.3.76 Transmit/Receive Status Copy Enable Register (TRSCER)
TRSCER specifies whether the information for the transmit and receive state reported by bits 17,
16, and 10 to 0 in the E-MAC/E-DMAC status register (EESR) is to be reflected in the TFE or
RFE bit of the corresponding descriptor. The bits in this register correspond to bits 17, 16, and 10
to 0 in EESR. When a bit is cleared to 0, the transmit status (bits 17 and 10 to 8 in EESR) is
reflected in the TFE bit of the transmit descriptor, and the receive status (bits 16 and 7 to 0 in
EESR) is reflected in the RFE bit of the receive descriptor. In this case, the state of a status bit set
to 1 is reflected as the TFE or RFE bit set to 1. When a bit is set to 1, the occurrence of the
corresponding source is not reflected in the descriptor. After this LSI is reset, all bits are cleared to
0.

R/W Description
R
Reserved
These bits are always read as 0. The write value should
always be 0.
R/W TABT Bit Copy Directive
0: Reflects the TABT bit status in the TFE bit of the
transmit descriptor
1: Occurrence of the corresponding source is not
reflected in the TFE bit of the transmit descriptor
R/W RABT Bit Copy Directive
0: Reflects the RABT bit status in the RFE bit of the
receive descriptor
1: Occurrence of the corresponding source is not
reflected in the RFE bit of the receive descriptor
