Notes to Table 14:

(1) To calculate tOH, use the following equation: tOH = 0.5 (DCLK period) - 2.5 ns.

(2) This parameter is used for CRC error detection by the FPGA.

(3) This parameter is used for CONF_DONE error detection by the EPC device.

(4) The FPGA VCCINT ramp time should be less than 1 ms for 2-ms POR and it should be less than 70 ms for 100-ms POR.
