4.9 Programming and Debug Interface
Important Note:
The SPI is for programming, configuring (PS Keys) and debugging the FSC-BT806A. It is required in production. Ensure
the 4 SPI signals are brought out to either test points or a header.
Feasycom provides development and production tools to communicate over the SPI from a PC, although a level
translator circuit is often required.
FSC-BT806A uses a 16-bit data and 16-bit address programming and debug interface. Transactions occur when the
internal processor is running or is stopped.
Data is written or read one word at a time, or the auto-increment feature is available for block access.
