When power (from 0 V) is applied to V

requirements”.
The RESET input can be asserted to initialize the system while keeping the V
operating level. A reset can be accomplished by holding the RESET pin LOW for a
minimum of t
changed to their default state once RESET is LOW (0). When RESET is HIGH (1), the I/O
levels at the P port can be changed externally or through the master. This input requires a
pull-up resistor to V

On power-up or reset, all registers return to default values.
