10. DTP/External Interrupt
The DTP (Data Transfer Peripheral) is a peripheral, positioned between peripherals external to the device and
the F
2
MC-16L CPU, that accepts DMA requests or interrupt requests generated by external peripherals and
transfers them to the F
2
MC-16L CPU to activate the Intelligent I/O Service or interrupt processing. In the case
of the Intelligent I/O Service, there are two request levels that can be selected: high and low; in the case of an
external interrupt request, there are a total of four request levels that can be selected: high, low, rising edge and
falling edge.
