Required Timing between Read and Write Commands
There are minimum timing requirements between read
and write commands on the serial port.
If the rising edge of the SCLK for the last data bit of the
second write command occurs before the required delay
(t
SWW
), then the first write command may not complete
correctly.
Timing between Two Write Commands
If the rising edge of SCLK for the last address bit of the
read command occurs before the required delay (t
SWR
),
the write command may not complete correctly.
Timing between Write and Read Commands
During a read operation SCLK should be delayed at least
t
SRAD
after the last address data bit to ensure that the
ADNS-5020-EN 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
SRR
or t
SRW
after the last SCLK rising edge of the last data bit of the
previous read operation.
