9. DTP/External Interrupt
The data transfer peripheral (DTP) is located between external peripherals and the F
2
MC-16F CPU. It receives
a DMA request or interrupt request generated by the external peripherals and reports it to the F
2
MC-16F CPU
to activate the extended intelligent I/O service or interrupt handler. The user can select two request levels of
“H” and “L” for extended intelligent I/O service (EI
2
OS) or, four request levels of “H,” “L,” rising edge, and falling
edge for external interrupt requests.
