Part Number: TDA4VM
I want to pull up a WKUP_GPIO0_19 pin of TDA4VM to 3.3V, why the output is always 1.8V? I am setting the GPIO in TI RTOS, could you please show me the interface in RTOS to setting the output of GPIO to 3.3V?
WKUP_GPIO0_19 falls under VDDSHV1_MCU(Balls H19, H21, J20) power(Refer TDA4VM Datasheet : "Table 4-1. Pin Attributes") and if VDDSHV1_MCU is 1.8V then WKUP_GPIO0_19(Ball D20) would be 1.8V output. And if VDDSHV1_MCU is 3.3V then WKUP_GPIO0_19(Ball D20) would be 3.3V output.
Thanks and Regards,
