DTP/External Interrupt
The DTP (Data Transfer Peripheral) is a peripheral block that interfaces external peripherals to the F
2
MC-16LX
CPU. The DTP receives DMA and interrupt processing requests from external peripherals and passes the
requests to the F
2
MC-16LX CPU to activate the extended intelligent
μ
DMAC or interrupt processing.
