SN65DSI86: GPIO4 PWM function

Hampton Hsia

Part Number: SN65DSI86

Hi Team,

We would like to know the status of GPIO4 when the DSI86 power just pulled high and not configured, input or output?

If it is an input function, what is the voltage level of GPIO4, pull high, pull low, or no pull?

Thanks,

Hampton,

SN65DSI86 GPIO4 defualts to an input after reset per GPIO4_CTRL bits. Please see 7.5 Electrical Characteristics for Vh and Vl of GPIO.

Hi Malik,

I mean does GPIO4 internally pull high, pull low, or no pull after reset per GPIO4_CTRL bits and GPIO4 defaults to an input.?

Thanks,

Hampton

Hampton,

GPIO4 has no pull after reset since it is an input after reset.
