    I am developing MK21. I connect the reset pin with 10k res and 1uf cap,and EZP_CS to ground. But after reset ,i only get 1.5V reset signal level. I observed the waveform, and found periodic oscillation. Then i remote the cap, and found the reset pin was kept low and suddenly flush to high shortly and then back to low,periodically.  Only connecting EZP_CS to high, the reset signal can be normal.  I don't know why.
