... UP_R/W or UP_CS signal. In Intel timing mode, the data is clocked into MT90225/226 pre-load register on the rising edge of the UP_R/W or UP_CS signal. Right after that transition, the data is transferred to the MT90225/226’s internal register. Writing data into this register can take up 2 system clock cycles. Zarlink Semiconductor Inc. 73 ...
