Layout is identical to ALARM3 in Lower Memory, Register 70h. Enables alarms to create TXFINT (Lower Memory,
Register 71h) logic. The MASK bit (Table 02h, Register 89h) determines whether this memory exists in Table 01h
or 05h.
BIT 7
TEMP HI:
0 = Disables interrupt from TEMP HI alarm.
1 = Enables interrupt from TEMP HI alarm.
BIT 6
TEMP LO:
0 = Disables interrupt from TEMP LO alarm.
1 = Enables interrupt from TEMP LO alarm.
BIT 5
VCC HI:
0 = Disables interrupt from VCC HI alarm.
1 = Enables interrupt from VCC HI alarm.
BIT 4
VCC LO:
0 = Disables interrupt from VCC LO alarm.
1 = Enables interrupt from VCC LO alarm.
BIT 3
MON1 HI:
0 = Disables interrupt from MON1 HI alarm.
1 = Enables interrupt from MON1 HI alarm.
BIT 2
MON1 LO:
0 = Disables interrupt from MON1 LO alarm.
1 = Enables interrupt from MON1 LO alarm.
BIT 1
MON2 HI:
0 = Disables interrupt from MON2 HI alarm.
1 = Enables interrupt from MON2 HI alarm.
BIT 0
MON2 LO:
0 = Disables interrupt from MON2 LO alarm.
1 = Enables interrupt from MON2 LO alarm.
