Hello,

I have a question of SPI on C6655 device.

This SPI doesn't have transmit-only and receive-only mode,

Can I use transmit(receive)-only by change from SPIDOUT(SPIDIN) to GPIO function in PIN_CONTROL_0 registers ?

Please tell me if other way.

Best regards, Chi

Chi,

You can use the PIN_CONTROL_0 register to control the pin mux selection between SPI and GPIO. Once those pins are configured as GPIO pins, you only have the GPIO functionality of these pins and they are no longer related to SPI functionality.

If it is what you plan to have, you could make the change in the register.

Hi Steven

Thank you for your reply.

I'd like to try changing the PIN_CONTROL_0 register.

Best regards,
