Layout is identical to ALARM 0 in Lower Memory, Register 73h. The MASK bit (Table 02h, Register 89h) determines
whether this memory exists in Table 01h or 05h.
LOS HI: Enables alarm to create TXFINT (Lower Memory, Register 71h) logic.

0 = Disables interrupt from LOS HI alarm.
1 = Enables interrupt from LOS HI alarm.
LOS LO: Enables alarm to create TXFINT (Lower Memory, Register 71h) logic.
0 = Disables interrupt from LOS LO alarm.
1 = Enables interrupt from LOS LO alarm.
RESERVED
BIAS MAX: Enables alarm to create internal signal FETG (see Figure 12) logic.
0 = Disables interrupt from BIAS MAX alarm.
1 = Enables interrupt from BIAS MAX alarm.
