Detailed Description

SPI buffer structure.

An SPI buffer describes either a real data buffer or an indication of NOP.

For a NOP indicator:

• If buffer is used for TX, only 0's will be sent for the length on the bus
• If buffer is used for RX, that length of data received by bus will be ignored/skipped
