13.6. Note on Interrupt during ISP/IAP
During ISP/IAP, the CPU halts for a while for internal ISP/IAP processing. At this time, the interrupt will queue
up for being serviced if the interrupt is enabled previously. Once the ISP/IAP is complete, the CPU continues
running and the interrupts in the queue will be serviced immediately if the interrupt flag is still active. Users,
however, should be aware of the following:
(1) Any interrupt can not be serviced in time during the CPU halts for ISP/IAP processing.
(2) The
external interrupts, /INT0, /INT1, /INT2 and /INT3, should keep active until the ISP/IAP
level triggered
is complete, or they will be neglected.
