Reset
During the assertion of the PORESET input signal, the chip assumes the default reset configuration. This
assumed configuration changes if the input signal RSTCONF is asserted when the PORESET is negated
or the CLKOUT starts to oscillate. To ensure 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 (defined as Tsup in the following figures) and the
maximum rise time of HRESET should be less than six 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.
