The customer of BYD can't turn on the LSDR0/1 of S12ZVR16 by use the following codes.
But creat a new project for S12ZVR32, It can turn on LSDR0/1 by use the following codes
and it run on S12VR32EVB bought from NXP.
If we replace S12ZVR32 on S12VR32EVB with S12ZVR16 , The PWM output function is normal, t also can't turn on the LSDR0/1 of S12ZVR16 by use the following codes.
It's very strange.

The S12ZVR16 is free samples by NXP, I think it should be all right.

/* Enable LSx power supply */
LSCR |= LSCR_LSE0_MASK;
LSCR |= LSCR_LSE1_MASK;

/* Enable LSx Over Current interrupt */
LSIE |= LSIE_LSOCIE_MASK;

//turn on LSDR0
LSDR |= LSDR_LSDR0_MASK;
