Serial Data Input Timing
Note: Data is shifted MSB first into the MICROWIRE shift register on the rising edge of the Clock signal. When a rising edge is seen on the LE pulse, these values
Note: The Serial Data Input Timing is tested using a symmetrical waveform around V
are actually loaded into the PLL target registers.
Since the data is clocked in on the rising edge of the LE pulse, the programming time of one register can be eliminated by sending the Data and Clock signals
in advance and delaying the LE pulse until it is desired that the values are to be loaded.
