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 intelligent I/O service or interrupt processing. Two request levels
(“H” and “L”) are provided for the intelligent I/O service. For external interrupt requests, generation of interrupts
on a rising or falling edge as well as on “H” and “L” levels can be selected, giving a total of four types.
