TPIC8101: TPIC8101

Part Number: TPIC8101

Hi

I'm working on a SPI communication between TPIC8101 and MCU Atmel Sam3x8E and have some questions:

1 From the product documentation I can't find which Transmission Format (clock phase and polarity controls) I should use?  

2 Must the Device Functional Mode be loaded in the specific sequence 1-6 ?

3 It would be nice if you could supply documentation for how the SPI register settings are handled, addresses and communication protocol for this device.

    1. Figure 1 in the datasheet shows this. It looks like CPOL = 0 and CPHA = 1

    2. The registers do not need to be loaded in order.

    3. There is no additional documentation beyond the datasheet, but it should have everything you need for implementing SPI. Most of sections 8.4 and 8.5 cover this topic.
