Description
Port 0.2. See Port I/O Section for a complete description.
Port 0.1. See Port I/O Section for a complete description.
Device Reset. Open-drain output of internal POR or V
An external source can initiate a system reset by driving this pin
low for at least the minimum RST low time to generate a system
reset, as defined in Table 2.7 on page 32. A 1 k pullup to V
is recommended. See Reset Sources Section for a complete
description.
