Note 3: After a reset from an in-circuit emulator, the IE_XFER flag may not be cleared because the CE may continue to run.
The flags for the RTC_1SEC and the XFER_BUSY interrupts are located in the WDI SFR (address 0xE8).
Interrupt Priority Level Structure
All interrupt sources are combined in groups, as shown in Table 45:
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 49 determines which request is serviced first.
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 44),
and these interrupts must be cleared by the MPU software.
An overview of the interrupt structure is shown in Figure 7.
