71M652X Software User’s Guide
All interrupt sources are combined in groups, as shown in Table 6-52. The priority of each group is controlled by the
bits of SFR registers IP1 and IP0.
Each group of interrupt sources can be programmed individually to one of four priority levels by setting or clearing one
bit in the special function register IP0 and one in IP1. If requests of the same priority level are received simultaneously,
an internal polling sequence determines which request is serviced first.
The functionality and edge polarity of the external interrupts are described in Table 6-51.
