Notes:
*1. RESET has an internal pull-up resistor of about 30 KΩ.
*2. P2 and P3.2−P3.4 can source a transition current when they are being externally driven from 1 to 0. The transition current
reaches its maximum value when VIN is approximately 2V.
*3. P3.0, P3.1, P4.4, P4.5, HIN, VIN and RESET are Schmitt trigger inputs.
