At power-on-reset, R, C, and D1 provide the necessary ramp rise time to reset the Micrel device. The reset out from CPU/FPGA
provides warm reset after power up. It is also recommended to power up the VDD core voltage earlier than VDDIO voltage.
At worst case, the both VDD core and VDDIO voltages should come up at the same time.
