Required timing between Read and Write Commands (tsxx)
There are minimum timing requirements between read and write commands on the serial port.
Figure 19. 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 50 microsecond required delay, then the first write command may not complete correctly.
Figure 20. Timing between write and read commands
If the rising edge of SCLK for the last address bit of the read command occurs before the 50
microsecond required delay, the write command may not complete correctly.
Figure 21. Timing between read and either write or subsequent read commands
The falling edge of SCLK for the first address bit of either the read or write command must be at
least 250 ns after the last SCLK rising edge of the last data bit of the previous read operation.
In addition, during a read operation SCLK should be delayed after the last address bit to ensure
that the ADNS-3080 has time to prepare the requested data.
