6. DTP/External Interrupts
The DTP (Data Transfer Peripheral) is a peripheral block that interfaces external peripherals to the F2MC-16L
CPU. The DTP receives DMA and interrupt processing requests from external peripherals and passes the
requests to the F2MC-16L CPU to activate the extended intelligent I/O service or interrupt processing. Two
request levels (“H” and “L”) are provided for extended intelligent I/O service. For external interrupt requests,
generation of interrupts on a rising or falling edge as well as on “H”, “L” levels can be selected, giving a total of
four types.
