Clicker 2 for PIC32MX employs a solution to optimize
the use of available pins and MCU I/Os. The PWM
SEL jumper (Figure 9-2) enables two modes of
use for the second available PWM line:
1
The default position of the jumper is for
applications when you’re not using the PWM line on
the 1x26 pinout on the right side of the board. This
keeps this PWM available through mikroBUS
2
2
If you resolder the jumper into the second
position, it would turn the PWM line on mikroBUS
2 into a GPIO. You would use this in scenarios
where you already utilized the PWM through the
1x26 pinout (which would make the PWM pin on
mikroBUS
2 unusable)
