Required Timing Between Read and Write Commands
There are minimum timing requirements between read
and write commands on the serial port.
Figure 15. Timing between two write commands
If the rising edge of the SCLK for the last data bit of the
second write command occurs before the required delay
(tSWW), then the first write command may not complete
correctly.
Figure 16. Timing between write and read commands
If the rising edge of SCLK for the last address bit of the
read command occurs before the required delay (tSWR),
the write command may not complete correctly.

DATA
During a read operation SCLK should be delayed at least
tSRAD after the last address data bit to ensure that the
ADNS-3550 has time to prepare the requested data. The
falling edge of SCLK for the first address bit of either the
read or write command must be at least tSRR or tSRW
after the last SCLK rising edge of the last data bit of the
previous read operation.
