The numbers in this table are based on the operating conditions set forth in
RDWR_B is synchronized to CCLK for the purpose of performing the Abort operation. The same pin asynchronously controls the
driver impedance of the D0 - D7 pins. To avoid contention when writing configuration data to the D0 - D7 bus, do not bring RDWR_B
High when CS_B is Low.
In the Slave Parallel mode, it is necessary to use the BUSY pin when the CCLK frequency exceeds this maximum specification.
Some Xilinx documents may refer to Parallel modes as "SelectMAP" modes.
