11. DTP/external interrupt circuit
DTP (Data Transfer Peripheral)/external interrupt circuit detects the interrupt request input from the external
interrupt input terminal INT7 to INT0, and outputs the interrupt request.
DTP/external interrupt circuit function
The DTP/external interrupt function outputs an interrupt request upon detection of the edge or level signal input
to the external interrupt input pins (INT7 to INT0).
If CPU accept the interrupt request, and if the extended intelligent I/O service (EI2OS) is enabled, branches to
the interrupt handling routine after completing the automatic data transfer (DTP function) performed by EI2OS.
And if EI2OS is disabled, it branches to the interrupt handling routine without activating the automatic data transfer
(DTP function) performed by EI2OS.
