Power Line Communication

Other Parts Discussed in Thread: TM4C123GH6PM, AFE031

I am working on Power Line Communication with AFE031 Analog front-end Modem. I have faced problem when I was interfacing AFE031 with Tiva C series Launchpad TM4C123GH6PM through SPI. In the datasheet of AFE031, it is written that command register should have 1 R/W bit and 6 bit register address(Page no. 35 under "Serial Interface"). But then in Table 8(Command Register, Page no. 35), it is written that in command register there will be 7 bit register address and one R/W bit. Which one is correct? Please give me Read and Write transaction of SPI for Reading Registers and for DAC also.

    Hello Rebanta,

    Writing to the AFE031 DAC is covered in section 2.2 of the following Applications report:

    Regarding the SPI register questions we are having to research them. We will get back to you when we have the information. We are coming up on the US Independence Day weekend and holiday so it will likely be mid, to late next week, before we have answers.

    Hello Rebanta,

    I was able to find and contact a TI employee who was at one time involved with the characterization of the AFE031. I sent him your inquiry and he provided me the information shown below. I hope this is what you need.
