DTP/External Interrupt
9.1 Outline
The DTP (Data Transfer Peripheral) is a peripheral block that interfaces external peripherals to the
2
F
MC-16LX CPU. The DTP receives DMA and interrupt processing requests from external peripherals and
passes requests to the F
interrupt processing. Two request levels ("H" and "L") are provideed for the extended intelligent I/O service
2
(EI
OS). For external interrupt requests, generating interrupts on a rising edge or falling edge as well as
"H" and "L" level can be selected, giving a total of four types.
