INTERRUPT SYSTEM
The ADuC832 provides a total of nine interrupt sources with
two priority levels. The control and configuration of the inter-
rupt system is carried out through three interrupt-related SFRs:
IE—interrupt enable register
IP—interrupt priority register
IEIP2—secondary interrupt enable register
IE (INTERRUPT ENABLE REGISTER)
SFR Address:
A8H
Power-On Default Value:
00H
Bit Addressable:
Yes
