INTERRUPT SYSTEM
The ADuC845/ADuC847/ADuC848 provide nine interrupt sources with two priority levels. The control and configuration of the
interrupt 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:
00H
Bit Addressable:
Yes
Table 58. IE SFR Bit Designations
Bit No.
