PULL
Any GPIO pin. Pull-up to IOVDD:
MODEn = DISABLE DOUT=1.
Pull-down to VSS: MODEn =
WIREDORPULLDOWN DOUT =
0.

MODE = INPUT, DOUT = 1 — 27 — ns
Note:
1. GPIO input thresholds are proportional to the IOVDD pin. RESETn input thresholds are proportional to DVDD.
2. GPIO pull-ups connect to IOVDD supply, pull-downs connect to VSS. RESETn pull-up connects to DVDD.
