Satus of device with RMII
interface at clock mode or
normal mode, default is
clock mode with 25MHz
Crystal clock from pins
X1/X2
(used for RMII of the
KSZ8895RQ only)
1 = The device is in clock mode when use RMII
interface, 25 MHz Crystal clock input as clock source
for internal PLL. This internal PLL will provide the 50
MHz output on the pin SMRXC for RMII reference
clock (Default).
0 = The device is in normal mode when use SW4-RMII
interface and 50 MHz clock input from external clock
through pin SM4TXC as device’s clock source and
internal PLL clock source from this pin not from the
25MHz crystal.
Note: This bit is set by strap option only. Write to this
bit has no effect on mode selection.
Note: The normal mode is used in SW5-RMII interface
reference clock from external.
