WAKE-UP by Link-Up Function
If this bit is enabled, MAC will drive wakeup pin whenever there is link-up
occurrence. The polarity of wakeup pin is according to bit0 of CMD
register.
1= enable
0= disable
WAKE-UP by Magic Packet
If this bit is enabled, MAC will drive wakeup pin whenever there is magic
packet detected by hardware. The polarity of wakeup pin is according to
bit0 of CMD register.
1= enable wake-up by magic packet
0 = disable
Reserved
Software Reset Internal PHY
Driver set this bit to ‘0’ to reset internal PHY. The reset duration is
depended on whenever this bit is de-asserted by deriver.
1 = in normal operation
0 = in reset status
Software Reset MAC
Driver set this bit to ‘0’ to reset MAC. The reset duration is depended on
whenever this bit is de-asserted by deriver. After power-on, driver must
activate software reset MAC once before initial other registers.
1 = in normal operation
0 = in reset status
Reserved
RX Remainder Capacity Upper-Bound
This field defines as upper bound of remainder size of RX buffer for pause
operation. If the flow control is enabled, MAC will stop to send pause
frame until the available space of receive buffer is more than this value.
The unit is 16-byte.
Reserved
RX Full Threshold
This field defines the least capacity of RX buffer. AX88780 will cause RX
full if it remains capacity less than this value. The unit is 16-byte.
