 ### interrupt.c
 Configures the Vectored Interrupt Manager and contains the corresponding 
 interrupt service routines (ISR).
   - PWM1 Parameter Interrupt
     - on falling edge of PWM1_SaP2_out (2 ms after H-bridge ON): read motor current
-    - on falling edge of PWM1_SaP1_out (~ 100 µs after H-bridge OFF): read Back EMF
+  - PWM2 Parameter Interrupt
+    - on falling edge of PWM2_S1P2_out (~ 400 µs after H-bridge OFF): read Back EMF
   - TMR0 (1 ms system clock)
