The data bus width is scalable (8/16/32 bit) to allow flexible integration with any CPU type. Operation in little or big endian mode is configurable through internal registers. The COMI address bus is 16 bit wide allowing direct access of up t0 64K words of the DPRAM. Two chip select signals are provided to allow splitting of the 64k address space in two memory banks. Host Control Interface (HOCI) gives read and write access to the TSS901E configuration registers and to the DS-Iink channels for the controlling CPU. Viewed from the CPU, the interface behaves like a peripheral that generates acknowledges to synchronize the data transfers and which is located somewhere in the CPU's address space. Packets can be transmitted or received directly via the HOCI. In this case the Com- munication Memory (DPRAM) is not strictly needed. However, in this case the packet size should be limited to avoid frequent CPU interaction. The data bus width is scalable (8/16/32 bit) to allow flexible integration with any CPU type. The byte alignment can be configured for little or big endian mode through an external pin. Additionally the HOCI contains the interrupt signalling capability of the TSS901E by providing an interrupt output, the interrupt status register and interrupt mask register to the local CPU. A special pin is provided to select between control of the TSS901E by HOCI or by link. If control by link is enabled, the host data bus functions as a 32-bit general pur- pose interface (GPIO). Protocol Command Interface (PRCI) that collects the decoded commands from all PPUs and forwards them to external circuitry via 5 special pins. JTAG Test Interface that represents the boundary scan testing provisions specified by IEEE Standard 1149.1 0f the Joint Testing Action Group (JTAG). The TSS901 E' test access port and on-chip circuitry is fully compliant with the IEEE 1149.1 specification. The test access port enables boundary scan testing of circuitry connected to the TSS901E I/O pins.
