1. The RTE V850 SB1 IE has a realtime trace function useful in debugging a built in system The realtime trace function can trace 32K cycles of any types including internal memory access cycles as driven by events A dedicated communication card is available for communication with the host Four different communication cards are available The PC card usable in the RTE V850 SB1 lE is a Type 2 card specified in PCMCIA Ver2 1 JEIDA Ver4 2 t can be used in the PC98 series and DOS V machine that have a card slot In desktop machines cards based on the C bus and ISA PCI bus can be used RTE V850 SB1 IE Hardware User s Manual 3 HARDWARE SPECIFICATION Emulation section V850 SB1 V850 SB2 Emulation function Automatic switching between external and internal clocks internal 20MHz 17 MHz 32 768 kHz 2 512 KB 24 KB 2MB External memory mapping unit 64 KB Memory mapping type RAM ROM GUARD USER Break function Event setting Execution address condition 14 points PAN Access cycle condition 4 points Available Available Fail safe break Available Available Trace function Event setting Execution address condition 2 points o Access cycle condition 3 points 150 bits x 32K words 0 7FFFh Time measurement function At the beginning of execution Till the occurrence of a break 2 CPU clock cycles 2 2 CPU clock cycles 1 ch Internal RAM realtime display 1 KB RESET NMI WAIT HLDRQ Available 4 0x000000 Ox2. RTE V850 SB1 IE and the CPU real chip The real chip allows the memory address output mode register MAM to be read and written while the RTE V850 SB1 IE allows the resister only to be written For the RTE V850 SB1 lE the subclock is factory set to 32 768 kHz Note that an oscillation circuit on the target is not used 10 RTE V850 SB1 IE Hardware User s Manual Cautions related to delay time Almost all signals are connected directly between the CPU in the IE and the user system see Appendix B However a delay of about 3 ns typical may occur due to the wiring length required in getting to the tip and the capacity compared with direct CPU connection The user system must be designed so as to accommodate this delay NQPACK set consumables 1 100 pin type F YQ socket YQS 100SDF E 2 100 pin YQ pack YQP 100SD with guide screws 3 100 pin NQ pack NQP 100SD Remark The sockets shown above are consumables They should be replaced regularly for example after about 50 cycles of insertion removal However a soldered socket at the lower surface of the RTE V850 SB1 IE cannot be replaced If it is expected that it is subjected to frequent insertion removal install a 100 pin YQ socket previously for protection purposes 11 RTE V850 SB1 IE Hardware User s Manual RTE V850 SB1 IE Hardware User s Manual M8B1MNLO1
