end of the packet.
Receiver error shall be asserted to indicate to MAC that an error
was detected. This signal should be synchronized with the RXC
signal.
This pin functions as the collision detection. When the external
physical layer protocol (PHY) device detects a collision, it
asserts this pin.
MII management data clock is sourced by the R1610C to the
external PHY devices as a timing reference for the information
transfer on the MDIO signal.
MII management data input/output transfers control information
and status between the external PHY and the R1610C.
To indicate PHY status changed.
JTAG function enable. Default is pulled low and disabled.

SDRAM clock ouput. This clock output is from internal De-skew
PLL. It can be one to four multiple of input clock X1, depending
on the setting of PDIVD [2:0] during power-on resets.
