3.4.4 Control Input Signals (/RES and /NMI)
The MCU control input signals are /RES and /NMI. The /RES and /NMI signals are only valid when emulation
was started with normal program execution (i.e., they are invalid when emulation was started with step
execution).
The input of the /RES or /NMI signal during execution or step execution can be disabled by a setting in the
[Configuration] dialog box.
3.4.5 Watchdog Timer (WDT)
When emulation is suspended (i.e. by a break), counting up by the WDT timer counter (TCNT) is also suspended.
Counting resumes when emulation is resumed (user mode).
During break mode, a prescaler, which supplies a clock to TCNT, operates continuously. Since the prescaler
might be in different phases before and after emulation goes through a period in the break mode, a break can
change the period before the WDT overflows by ±1 cycle of the prescaler’s clock.
3.4.6 A/D Converter
As well as analog input pins, the A/D converter has AVcc, AVss, and /ADTRG pins. As the A/D converter
operates with an independent power supply, connect AVcc (the power supply pin) to the A/D power supply on
the user system.
Notes: 1. When the A/D converter is not in use, connect AVcc to Vcc.
2. As there are user system interface cable, compression circuits (for compression at the ratio of 5:3.3),
wiring on the printed circuit board, and protective circuits are connected between the user system
and the MCU on the evaluation chip board, the precision of conversion is lower than that of the
actual MCU.
