we want connect PE64904 device ( e wire SPI compatible interface) to stm32f407

There is nothing to read from this device.
You can use SPI, and ignore the Rx values.
Half duplex basically means sequentially alternating transmission direction. In difference to full duplex, were both appens at the same time.
Both is not relevant for your device, because it is write-only.

so i need use fullduplex definition or half duplex or transmit master only ?

whatever you choose, it will be the same for the application.

so why you wrote "Both is not relevant for your device"

Transmit only master makes the most sense, since that's all you need it to do.
