Figure 16: SPI Slave Port: Typical Read and Write operations
Possible applications for the SPI interface are:
1) An external host reads data from CE locations to obtain metering information. This can be used in
applications where the 71M6531D/F or 71M6532D/F function as smart front-ends with preprocessing
capability. Since the addresses are in 16-bit format, any type of XRAM data can be accessed: CE,
MPU, I/O RAM, but not SFRs or the 80515-internal register bank.
2) A communication link can be established via the SPI interface: By writing into MPU memory locations,
the external host can initiate and control processes in the MPU of the 71M6531D/F or 71M6532D/F.
Writing to a CE or MPU location normally generates an interrupt, a function that can be used to signal
to the MPU that the byte that had just been written by the external host must be read and processed.
Data can also be inserted by the external host without generating an interrupt.
3) An external DSP can access front-end data generated by the ADC. This mode of operation uses the
71M6531D/F or 71M6532D/F as an analog front-end (AFE).
