2 pin connections to control the key
#1
Hi everyone,

In the PineTime schematic v1.0, the main button (J6 KEY) is connected to the nRF52832 MCU pins P0.13 and P0.15, both circuits are pulled-down externally and receiving VCC33 when key is pressed.


I can not figure out the motivation to use  2 MCU pins to control the key. May be is it intended to detect whether the key is there, in the case?    Confused  



Regards,
Rafa
