Table 05h, F9h: Alarm Masks
FACTORY DEFAULT:
MEMORY TYPE:
The MASK configuration bit (Table 04h (Table 01h in DS1859 configuration), register DAh, bit 0) determines which mask sets are
used to generate the MINT interrupt.
one of the interrupts is desired, its bit must be written to a 1 here. If no interrupt is desired, the bit should be written to a 0.
These bytes configure a maskable interrupt, determining which alarm flags assert the MINT bit (Lower Memory, byte 71h, bit 0). If
