Data Sheet
The PSB 4860 offers the possibility to transfer the speech data via SCI. To use this
feature, the SCI bit in register SDCTL must be set. The speech decoder reads the
speech data from register SDDATA. Bit DRQ in register STATUS indicates when new
data is requested from SDDATA and the microcontroller must then write this data. When
the microcontroller writes the data, the DRQ bit is cleared. Table 37 shows the registers
involved.
