 PWM (Pulse Width Modulation) capability allows a digital pin to emulate analog output by flickering on and off very fast letting you, among other things, dim LEDs connected to digital pins. 
 
-The UNO R4 Minima has six PWM-capable pins marked with ~ on the headers. The PWM-capable pins are:
-
-- D3~
-- D5~
-- D6~
-- D9~
-- D10~
-- D11~
+The UNO R4 Minima supports PWM on pins marked with ~ on the headers. Officially supported pins are:
+
+| Pin | RA4M1 | Timer   |
+| --- | ----- | ------- |
+| D3  | P104  | GTIOC1B |
+| D5  | P102  | GTIOC2B |

 You may use them as analog output pins with the function:
