MSPM0G1107: Fail to configure TIMA1 compare Pin 1 to PB7

Part Number: MSPM0G1107

Tool/software:

Hi team,

My customer is developing with M0G1107. They want to use TIMA1 for PWM, While configuring TIMA1 compare Pin 1 to PB7, it shows error "PB7/59 is only available on TIMG6,TIMG8 which is in use by CAPTURE_0 ,CAPTURE_1".

However, the document describes theTIMA1_C1N .can be used. 

Please clarify it's the limitation to configure TIMA1 compare Pin 1 to PB7 ? else, there is something wrong while customer do configuration.

Thank you.

    Hi Jerry,

    As picture shows above, TIMA1_C1N is TIMA  CCR1 compare inverting output, which means if you want to use complementary output, you can enable PB7 as complementary output of TIMA channel 1. If complementary output is not required, PB7 cannot be configured as a regular PWM output while using TIMA. You can tell the customer to do the test as follows.

    Step1: Enable Channel Complimentary Output.

    Step2: Choose PB7 as inverting output of channel 1.

    Best Regards,

    Peter
