Part Number: TPS65988

Hi Team,

Would you advise that do these pins have GPIO function?

36：SPI_MISO

37：SPI_MOSI

38：SPI_CLK

39：SPI_SS

Because there is GPIOxx pin name description on page3 however

no GPIO pin name on page5 in datasheet revA(REVISED AUGUST 2018).

Thanks

Best regards,

Hi Shidara,

Is your application running out of GPIOs? I would like to understand the reason behind using these GPIOs.

Thanks

Hi Prajith-san

I expect my customer would like to use these pins as GPIOs in case of

not using as SPI communication thru these pins.

Thanks

Best regards,

Hi Shidara,

We do not support multiplexing SPI pins with GPIO.

Hi Prajith-san

Thanks for your reply.

I understood.

Would you remove GPIOxx description on Pin# from 36 to 39 below on page 3 in datasheet ?

Thanks

Best regards,

Shidara
