in Lower Memory, Register 70h. Enables alarms to create TXFINT (Lower Memory,
Register 71h) logic. The MASK bit (A2h Table 02h, Register 89h) determines whether this memory exists in A2h
Table 01h or 05h. When in A2h Table 05h, this location at A2h Table 01h becomes EE.
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
TXB HI:
0 = Disables interrupt from TXB HI alarm.
1 = Enables interrupt from TXB HI alarm.
BIT 2
TXB LO:
0 = Disables interrupt from TXB LO alarm.
1 = Enables interrupt from TXB LO alarm.
BIT 1
TXP HI:
0 = Disables interrupt from TXP HI alarm.
1 = Enables interrupt from TXP HI alarm.
BIT 0
TXP LO:
0 = Disables interrupt from TXP LO alarm.
1 = Enables interrupt from TXP LO alarm.
