DPC31 HW Description

Interrupt EOI Register, EOI (writable, can be changed during operation)

EOI is triggered with the write operation to the register cell ‘Interrupt EOI Register’. The write data is don’t

care.

7.2 Synchronous Serial Interface (SSC Interface)

In the DPC31, a universal synchronous serial interface is integrated. In addition, several SPI slave blocks

(ser. E²PROMs or AD transformers) can be connected to this interface (Figure 7.2-1). This SSC interface has

full duplex capability, and only supports the master mode.
