5 / 24 page  ADSST-SALEM-3T Rev. 0 | Page 5 of 24 Efficient data transfer is achieved with the use of five internal buses: • Program Memory Address (PMA) Bus Program Memory Data (PMD) Bus • Data Memory Address (DMA) Bus • Data Memory Data (DMD) Bus • Result (R) Bus The byte memory and I/O memory space interface supports slow memories and I/O memory-mapped peripherals with pro- grammable wait state generation. External devices can gain control of external buses with bus request/grant signals (BR, BGH, and BG0). One execution mode (go mode) enables the ADSST-218x to continue running from on-chip memory. Nor- mal execution mode requires the processor to halt while buses are granted. The ADSST-218x can respond to 11 interrupts. There are up to six external interrupts (one edge sensitive, two level sensitive, and three configurable) and seven internal interrupts generated by the timer, the serial ports (SPORTs), the byte DMA port, and the power-down circuitry. There is also a master RESET signal. The two serial ports provide a complete synchronous serial interface with optional companding in hardware and a wide variety of framed or frameless data transmit and receive modes of operation. Serial Ports The ADSST-218x incorporates two complete synchronous serial ports (SPORT0 and SPORT1) for serial communications and multiprocessor communication. Package Description The ADSST-218x is available in a 100-lead low profile quad flat package (LQFP, refer to Figure 5). |
