MSPM0G3507: Power Policy Management

Hi team,

I'm trying to implement a low power mode in our desing with the MSPM0G3507. Regarding to this, I cannot achieve waking up the MCU from a TIMG0 interrupt. Can I wake up the MCU from this IRQ in STOP or STANDBY mode? Because in page 98 from the MCU datasheet refers to PD0 IRQ as waking up source. By the way in page 1361 refers that TIMG0 is powered up by PD0.

I'm using the MSPM0G3507 EVM and this code
