DPR Registers for 680 Correctable Machine

Check Logout Frames

DPR Locations A0:A9 represent the information that the console will

read when a 680 machine check logout frame is loaded. They provide

the interrupt information obtained by the RMC through the LM78

sensors. When an error occurs, the RMC writes the bits and delivers an

IRQ to the SRM console. The SRM reads the bits and clears them. On

the next 680 error, the RMC writes the error into the A0:A9 locations.
