DocID025109 Rev 1

Read and write operations are persistently executed while CSn is kept active (low), the

address being automatically incremented (burst mode).

Accessing the FIFO is done as usual with the read and write commands, by putting, as the

address, the code 0xFF. Burst mode is available to access the sequence of bytes in the

FIFO. Clearly, TX-FIFO with a write operation.

Details of the SPI parameters are reported below.

Interrupts

In order to notify the MCU of a certain number of events an interrupt signal is generated on

a selectable GPIO. The following events trigger an interrupt to the MCU:
