As the address detection system, the brake address register compari- 6. SSP circuit son system is employed though the mapping system was employed in the conventional monitor RAM. The address registerlocated in MPCA 1) Block diagram is always compared with the system address bus to monitor and gen- erate NMI signal at a synchronized timing and togo to NMI exception This is the circuit employed to do the Special Service Preset(SSP).

3) SSP register access method Access to SSP break address register is performed through the tem- porary register as shown below: A19 A18 A17 A16 A15 A8 A7 Temporary Temporary Fig. 6-5 Enable flags can be accessed individually. Information on which brake register the SSP brake is detected in is Though enable register 4 can be accessed individually, writing to read as binary data by reading address FFFFFFH (*1).
