Hi everyone,

I design a PCB with PWM on LPC1114 and I need to use PWM1.0 (PIO1.1/MAT0 Timer 1 32b), PWM1.1 (PIO1.2/MAT1 Timer 1 32b) and PWM1.3 (PIO1.4/MAT3 Timer 1 32b) outputs.

I am reading an user manual of LPC1114 and I am wondering is it possible to use PWM1.3/MAT3 as PWM output?
In the user manual is written:
Chapter: 21.7.12
Table: 342
Rev.: 12.1

PWMEN3 PWM channel 3 enable
Note: It is recommended to use match channel 3 to set
the PWM cycle.

Hi, Teslabox,
It is recommended to use the match registers that are not pinned out to control the PWM cycle length.
MAT3 is not pin out and can not work as PWM output but can be used to set the PWM cycles.
