Table 05h, FBh: Warning Masks
FACTORY DEFAULT:
MEMORY TYPE:
A 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 warning flags assert the MINT bit (Lower Memory, byte 71h, bit 0). If

MON3wrnhimask: Determines if an interrupt is generated for a High MON3 Warning Flag.
0 = No interrupt is generated.
1 = An interrupt is generated.
