Section 23 Gigabit Ethernet Controller (GETHER)
After the reception processing of the frame, the next descriptor reading standby state begins. At
this time, if 32 bytes or more of data or the last byte of the receive frame is stored in the receive
FIFO, the next receive descriptor process is performed continuously.
When the TACT bit of the read receive descriptor is 0 (invalid), the receive descriptor empty state
is determined and the RDE bit in EESR is written to 1, and then an interrupt is issued to the CPU.
To receive frames continuously, set the RNC bit in RMCR to 1. The initial value is 0.
