Application Examples
If yes, halt the system, awaiting system battery
replacement (for systems powered by battery only)
If no, read SLIN* (bit 3) at the Printer Port
Control register at address 037Ah.
If set to 1, continue to read the bit and check.
Power-fail condition persists.
If set to 0, power-fail has resulted in a brownout
condition, and the system did not need to stop
(Vcc remained above 4.75 V). Call the RESET
routine.
Return from interrupt
If set to a 0, the NMI was the result of the 8087
mounted on the ZT 8809A, or from an NMI request
from the backplane. Resolve this according to the
system needs. Return from interrupt.
