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.
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.
TMPwrnhimask: Determines if an interrupt is generated for a High-Temperature Warning Flag.
