Required Timing between Read and Write Commands
There are minimum timing requirements between read and write commands on the serial port.
SCLK
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
then the first write command may not complete correctly.
SCLK
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
command may not complete correctly.
SCLK
Timing between Read and Subsequent Write or Read Commands
During a read operation SCLK should be delayed at least t
has time to prepare the requested data. The falling edge of SCLK for the first address bit of either the read or write com-
mand must be at least t
