These bytes configure a maskable interrupt, determining which alarm flags assert the MINT bit (Lower Memory, byte 71h, bit 0). If
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 bit locations do not match the register locations as called out in the SFF-8472, therefore another four byte set is also stored in
another location (Table 05h, registers F8h to FBh). The MASK configuration bit (Table 04h (Table 01h in DS1859 configuration),
register DAh, bit 0) determines which mask sets is used to generate the MINT interrupt.
MONalm3himask: Determines if an interrupt is generated for a High MON3 Alarm Flag.
bit7
bit6
bit5:0
0 = No interrupt is generated.
1 = An interrupt is generated.
MON3almlomask: Determines if an interrupt is generated for a Low MON3 Alarm Flag.
0 = No interrupt is generated.
1 = An interrupt is generated.
Reserved.
