I saw the following description in the above Wiki.
1. SYS_NRESWARM is pulled-low when SYS_NRESPWRON is LOW.
2. Once SYS_NRESPWRON goes HIGH, for PRM_RSTTIME, SYS_NRESWARM will be driven LOW (No pull down).
3. After that SYS_NRESWARM will be pulled high internally.
I guess that the above description is the same as follows.
1. SYS_NRESWARM is L (High-impedance with an active pulldown registor) when SYS_NRESPWRON is LOW.
2. Once SYS_NRESPWRON goes HIGH, for PRM_RSTTIME, SYS_NRESWARM will be PD (The buffer drives VOL with an active pulldown registor).
3. After that SYS_NRESWARM will be H (High-impedance with an active pullup resistor).
Is the state of SYS_NRESWARM after the power-on reset H (High-impedance with an active pullup resistor)?
