12. DTP/External Interrupt Circuit
The DTP (Data Transfer Peripheral)/external interrupt circuit is located between peripheral equipment connected
externally and the F2MC-16L CPU and transmits interrupt requests or data transfer requests generated by
peripheral equipment to the CPU, generates external interrupt request and starts the extended intelligent I/O
service (EI2OS).
