CPU board block diagram, B-CPU5/B-CPU4

The CPU board, B-CPU5/B-CPU4 is made with PC-technology components. Radisys chipset and

PLD handle all timings and signaling for ISA type CPU bus.
The B-CPU5/B-CPU4 contains an onboard flash memory where software is downloaded from a

software card.

Powerfail or standby

When the monitor is turned to standby or the mains voltage fails, NMI-interrupt is generated by the

power control logic. The interrupt signal in the CPU means that all supply voltages 5V for

the CPU board will be switched off shortly. NMI interrupt service program then saves all necessary

parameters in the static RAM before supply voltages fail.
When hardware detects HALT command generated from power down; all the outputs to the CPU

motherboard are left floating in high impedance state. Only DRAM refreshing cycle continues to

occur. The halt state will continue until a RESET pulse from the power control logic circuit is

received.
