Required Timing between Read and Write Commands (tsxx)
There are minimum timing requirements between read
and write commands on the serial port.
SCLK
Figure 25. Timing between two write commands.
If the rising edge of the SCK for the last data bit of the
second write command occurs before the 100 µs required
delay, then the first write command may not complete
correctly.
SCK
Figure 26. Timing between write and read commands.
If the rising edge of SCK for the last address bit of the read
command occurs before the 100 µs required delay, then
the write command may not complete correctly.
SCK
Figure 27. Timing between read and either write or subsequent read commands.
The falling edge of SCK for the first address bit of either
the read or write command must be at least 250 ns after
the last SCK rising edge of the last data bit of the previous
read operation.
