I am reading the schematic of a microcontroller (SODAQ ONE V3 which is based on Arduino Zero) in order to design my own PCB with my components embedded in a chip. I would like to know what this notation means (eg. 1*2 in a symbol pin/terminal):
MCP73831 symbol (this is the battery charging module that the microcontroller uses to charge if battery is connected, the manufacturer is microchip.
I have been reading how to read electronics schematics in different blogs and posts like this but I did not find the answer. (How to read schematics).
