DATA SHEET
NOVEMBER 2010
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 45), and these interrupts must be cleared by the MPU software.

Table 44: External MPU Interrupts
Interrupt 6 is edge-sensitive. The RTC_1SEC interrupt from the RTC and the XFER_BUSY interrupt from the CE are com-
bined using a logic OR function and the result is routed into interrupt 6. Therefore, both flags must be cleared at least once
during initialization, and both flags must always be cleared before exiting the interrupt service routine (ISR) for interrupt 6.
Note 1: If clearing of both flags is not performed, then no edge can occur to trigger interrupt 6 later resulting in the ISR for the
XFER_BUSY ceasing to run.
Note 2: Clearing both flags reliably requires some care. Either flag can be set by hardware while interrupt 6 code is running on
behalf of the other interrupt. In this situation, the unprocessed interrupt can create a lockout condition similar to the one in note
1. To prevent this lockout one must always process both interrupt flags in the same service routine.
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).
