<4> Install the IE-780862-NS-EM1 in the IE-78K0-NS or IE-78K0-NS-A.
(3) When inputting pulse from target system
No hardware settings are required for this situation.
When starting the integrated debugger (ID78K0-NS), open the configuration dialog box and select “External” in
the area (Clock) for selecting the CPU’s clock source (this selects the user’s clock).
After the debugger is activated, if “X1orRC” is selected for the mask option SystemClock in the Mask Option
dialog box and the SFR MCM0 is changed to 1, the CPU operating clock is switched from the low-speed Ring-
OSC to the clock input from the target system.
(4) When using on-chip Ring-OSC
(a) When using high-speed Ring-OSC
No hardware settings are required for this situation. After the integrated debugger (ID78K0-NS) is activated,
if “HighspeedRing” is selected for the mask option SystemClock in the Mask Option dialog box and the SFR
MCM0 is changed to 1, the CPU operating clock is switched from the low-speed Ring-OSC to the high-speed
Ring-OSC on the emulation board.
(b) When using low-speed Ring-OSC
The low-speed
Ring-OSC (240 kHz) is selected as the CPU operating clock when the IE system is activated.
See
3.2.2 (1)
to
(4)
when changing the setting.
Caution
Use of the peripheral functions, except for the following cases, is prohibited when the
low-speed Ring-OSC is selected as the CPU operating clock (MCM0 = 0).
When watchdog timer is used
When clock monitor is used
TMH1 (When fosc/2
When peripheral function that uses an external clock as the operating clock is used
