Figure 11. 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 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.
