bit7

bit0

These bytes configure a maskable interrupt, determining which warning 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.

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.

bit7

MON3wrnhimask: Determines if an interrupt is generated for a High MON3 Warning Flag.

0 = No interrupt is generated.

1 = An interrupt is generated.

bit6

MON3wrnlomask: Determines if an interrupt is generated for a Low MON3 Warning Flag.

0 = No interrupt is generated.

1 = An interrupt is generated.

bit5:0

Reserved.
