Required Timing between Read and Write Commands
There are minimum timing requirements between read
and write commands on the serial port.
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
(t
correctly.
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 (t
the write command may not complete correctly.
Timing between Read and Either Write or Subsequent Read Commands
During a read operation SCLK should be delayed at least
t
ADNS-5050 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 t
the last SCLK rising edge of the last data bit of the previous
read operation.
