MSPM0C1104: how many PWM be supported?

Part Number: MSPM0C1104


Hi, experts:

     As shown in <MSPM0C110x, MSPS003 Mixed-Signal Microcontrollers>, P1:

Three timers supporting up to 14 PWM channels

• One 16-bit advanced timers with deadband support up to 8 PWM channels 

but in P34, only support 8 pwm in total:

Two independent channels for TIMGx and  four independent channels for TIMAx, I'm confused about this, and in CCS Theia 1.3.1 I can only set max 8 pwm channels, can you clarify it? Thanks.

    Hi, bill.liao

    Here is the example .syscfg file that have max 14 PWM output configuration.

    https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/908/3858.timx_5F00_timer_5F00_mode_5F00_pwm_5F00_edge_5F00_sleep.syscfg

    A error that TIMA0,CC2N conflicts with the SWD interface. You need to disable the SWD interface to use this PWM normally.

    Hi, Helic:

          If TIMG14 is set to 4 channels of PWM, it will come out a compile error:
