This library provides PWM output using the MAX32630 32-bit timers.
The mbed PwmOut API implementation uses the MAX32630 Pulse Train peripherals.
The table below contains the available GPIO pins that can be connected to the six 32-bit timers (TMR0-5). Timer 0 is used for the microsecond ticker API and is not available for PWM output. Timer 5 is used by the BLE API and will not be available for PWM output if the BLE API is used.
| Timer | GPIO Port and Pin |
| TMR1 | P3_1, P5_3 |
| TMR2 | P2_4, P3_2, P4_0, P5_4 |
| TMR3 | P2_5, P3_3, P5_5 |
| TMR4 | P2_6, P3_4, P5_0, P5_6 |
| TMR5 | P3_5, P5_1 |
Note GPIO P2_4, P2_5 and P2_6 are connected to onboard LEDs 1, 2 and 3.
