Other Parts Discussed in Thread: CC2530

I have some questions about Zstack commands using ZNP. I am very confused about the different kinds of commands AREQ, SREQ, POLL what are the difference between each one of them?

also is SYS_RESET_IND AREQ or POLL??

 in bytes which CC2530 sends data to host processor, if host processor sends dummy bytes on MOSI is this a problem?or CC2530 ignores these data bytes anyway?

    1. POLL: A POLL command is used to retrieve queued data. This
    command is only applicable to SPI transport. For a POLL command the
    subsystem and Id are set to zero and data length is zero.

    2. SREQ: A synchronous request that requires an immediate response. For
    example, a function call with a return value would use an SREQ command.

    3. AREQ: An asynchronous request. For example, a callback event or a
    function call with no return value would use an AREQ command

    4. There should be no problem if host sends dummy bytes to CC2530.
