For the application where the reset circuit signal comes from another device (e.g., CPU, FPGA, etc), the following reset circuit
is recommended.

Recommended Circuit for Interfacing with CPU/FPGA Reset
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 recommend to power up VDD core voltage earlier
than VDDIO voltage. At worst case, the both VDD core and VDDIO voltages should come up at the same time.
