The voltage at the (–) pin of the comparator IC7A is always maintained to 5.1V by means of the zener diode ZD2, while +24V supply voltage is divided through the resistors R114, R115 and R116, and is applied to the (+) pin. When normal +24V is in supply, 6.8V is supplied to the (+) pin, therefore, signal POFF is at a high level. When +24V supply voltage decreases due to a power off or any other reason, the voltage at the (+) pin also decreases.

As the address detection system, the break address register comparison system is employed though the mapping system and employed in the conventional monitor RAM. The address register located in MPCA is always compared with the system address bus to monitor and generate the NMI signal at a synchronized timing and to go to the NMI exception process. In the exception process routine of the service routine, the entry address is checked to go to the SSP sub routine.
3) SSP register access method Access to SSP break address register is performed through the temporary register as shown below: A19 A18 A17 A16 A15 A8 A7 A2 EN Temporary Temporary 4 WR 1 2 3 WR Fig. 6-5 Information on which break register the SSP break is detected and is read as binary data by reading address FFFFFFH (*1).
