RQ: Select the data sampling edge of Switch MAC5
SW5- RMII reference clock:
1 = data sampling on negative edge of refclk
0 = data sampling on positive edge of refclk (default)
Note:MQ/FMQ is reserved with read only for this bit.

Select the SPI/SMI clock edge for sampling SPI/SMI
read data.
1 = trigger by rising edge of SPI/SMI clock (for high
speed SPI about 25MHz and SMI about 10MHz)
0 = trigger by falling edge of SPI/SMI clock.
