The numbers in this table are based on the operating conditions set forth in
Some Xilinx documents refer to Parallel modes as “SelectMAP” modes.
It is possible to abort configuration by pulling CSI_B Low in a given CCLK cycle, then switching RDWR_B Low or High in any subsequent
cycle for which CSI_B remains Low. The RDWR_B pin asynchronously controls the driver impedance of the D0 - D7 bus. When RDWR_B
switches High, be careful to avoid contention on the D0 - D7 bus.

The time from the setup of data at the D0-D7 pins to the rising transition at the CCLK pin
Setup time on the CSI_B pin before the rising transition at the CCLK pin
Setup time on the RDWR_B pin before the rising transition at the CCLK pin
The time from the rising transition at the CCLK pin to the point when data is last held at
the D0-D7 pins
The time from the rising transition at the CCLK pin to the point when a logic level is last
held at the CSO_B pin
The time from the rising transition at the CCLK pin to the point when a logic level is last
held at the RDWR_B pin
The High pulse width at the CCLK input pin
The Low pulse width at the CCLK input pin
Frequency of the clock signal
at the CCLK input pin
