9. DTP/External Interrupt
The DTP (Data Transfer Peripheral) is a peripheral, positioned between peripherals external to the device and
the F2MC-16L CPU, that accepts DMA requests or interrupt requests generated by external peripherals and
transfers them to the F2MC-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.

10. Watchdog Timer, Timebase Timer, and Watch Timer Functions
The watchdog timer consists of a 2-bit watchdog counter that uses the carry signal from the 18-bit timebase
timer or the 15-bit watch timer as a clock source, a control register, and a watchdog reset controller.
The timebase timer consists of an 18-bit timer and a circuit that controls interval interrupts. Note that the timebase
timer uses the main clock, regardless of the setting of the MCS bit and SCS bit in CKSCR.
The watch timer consists of a 15-bit timer and a circuit that controls interval interrupts. Note that the watch timer
uses the sub clock, regardless of the setting of the MCS bit and SCS bit in CKSCR.
