SPI read of MAX31856 in Verilog

Question

1. I am trying to read the K-type thermocouple temperature with MAX31856 in Verilog.
2. Configured the configuration registers CR0 & CR1.
3. The conversion result is stored in the registers 0xC, 0XD, 0XE. I have to read these registers using a SPI state machine.
4. What timings should I have to cater for?
5. The only timing constraint I found in data sheet is the update rate of 100ms. Which means for cycle reads you have to wait for 100ms for new results. But the data sheet shows that conversion results are available after 110ms? Why this figure violating the update rate (100ms)?
6. In SPI read for burst mode (auto increments to D and E registers) do I have to send the address of register C only? Or do I have to send ADDRESS of register 0xC with dummy bytes?

Answer 1

4. All of them.

5. Not sure which numbers you're looking at, but it isn't really important.

6. Figure 6 in the datasheet is fairly clear on this.

Similarly, Figure 7 is clear about the overall protocol: You wait for DRDY- to go low, then you execute the 3-byte read of registers C, D and E, during which DRDY- will go high again. The specific timing at which this happens (update rate) depends on the chip configuration, as described at the bottom of page 4.
