15.1 Interrupt SFRs
The following SFRs are associated with interrupt control:
- IE – SFR 0xA8 (Table 37)
- IP – SFR 0xB8 (Table 38)
- EXIF – SFR 0x91 (Table 39)
- EICON – SFR 0xD8 (Table 40)
- EIE – SFR 0xE8 (Table 41)
- EIP – SFR 0xF8 (Table 42)
The IE and IP SFRs provide interrupt enable and priority control for the standard
interrupt unit, as with industry standard 8051. The EXIF, EICON, EIE, and EIP registers
provide flags, enable control, and priority control for the extended interrupt unit.
