RMII Receive Data [1:0]:
The RTL8316 samples the receive data
RXD[1:0] on the rising edge of REFCLK when CRSDV is high.
I
RMII Reference Clock input:
A 50 MHz signal is used for the
RMII clock reference and is used to generate an internal 66 MHz
system clock.

Description
RST#
System Reset:
Active low to reset the system to a known state. After
power-on reset (low to high), the configuration modes from Mode
Pins are sampled and determined, then RTL8316 will start to access
the management register of PHY devices and restart the
Auto-negation.

P12TXE
Description
EnP14ForceMode
Port 14 Force Mode Setup Enable:
Pulled high upon reset will
enable port 14 to set flow control, duplex mode and speed by
P14FCTRL, P14DUPLEX and P14SPEED pins separately.
Otherwise, these setups will depend on port 14 auto-negotiation
results.
1: Enable force mode setting
0: Disable force mode setting (Default)
P12TXD0
Port 14 Flow Control Force Mode Setup:
During RST# rising
edge, if EnP14ForceMode = High, this pin acts as port 14s flow
control force mode setup pin, set as below:
1: Force enable flow control. (Default)
0: Force disable flow control.
P13TXD0
Port 14 Duplex Force Mode Setup:
During RST# rising edge, if
EnP14ForceMode = High, this pin acts as port 14s duplex force mode
setup pin set as below:
1: Force full duplex mode. (default)
0: Force half duplex mode
