CAM Command Register (CAMCMR_0, CAMCMR_1)
The three accept bits in the CAMCMR_x are used to override CAM rejections or accept ion. To place the
MAC in promiscuous mode, use CAMCMR_x settings to accept packets with all three types of
destination address. The three types of destination address packets are as follows:
DMA REGISTERS
TXDLSA_1
RXDLSA_1
