USER’S MANUAL
that stable data is sampled, the hardware configuration is sampled every eight clock
cycles on the rising edge of CLKOUT with a double buffer. The setup time required for
the data bus is approximately 15 cycles, and the maximum rise time of HRESET
should be less than 6 clock cycles. In systems where an external reset configuration
word and the TEXP output function are both required, RSTCONF should be asserted
until SRESET is negated.
