Interrupt Priority Level Structure
All interrupt sources are combined in groups, as shown in Table 48:

External interrupt 2
External interrupt 3
External interrupt 4
External interrupt 5
External interrupt 6
Table 48: Priority Level Groups
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 as per Table 52 determines which request is serviced first.
An overview of the interrupt structure is given in Figure 6.
IEN enable bits must be set to permit any of these interrupts to occur. Likewise, each interrupt has its own flag bit that
is set by the interrupt hardware and is reset automatically by the MPU interrupt handler (0 through 5). XFER_BUSY
and RTC_1SEC, which are OR-ed together, have their own enable and flag bits in addition to the interrupt 6 enable
and flag bits (see Table 47) and these interrupts must be cleared by the MPU software.
