●
Precautions on interrupts
•
When the DTP/external interrupt is used as the external interrupt function, no return from interrupt
processing can be made with the DTP/external interrupt request flag bit set to "1" (EIRR: ER) and the
DTP/external interrupt request set to enabled (ENIR: EN = 1). Always set the DTP/external interrupt
request flag bit to "0" (EIRR: ER) at interrupt processing.
•
When the level detection is set in the detection level setting register and the level that becomes the
interrupt factor remains input, the external interrupt request flag bit is reset immediately even when
cleared (EIRR: ER = 0).Disable the DTP/external interrupt request output as needed (ENIR: EN = 0), or
cancel the interrupt factor itself.
