QB-RL78L12 In-Circuit Emulator
Remark Insert the oscillator into the socket, take care for the pin 1 position.
(2) Internal high-speed oscillation clock
This method uses the clock inside the emulator by configuring the use of the high-speed oscillation clock in the
user program.
(3) Internal low-speed oscillation clock
This method uses the clock inside the emulator by configuring the use of the low-speed oscillation clock in the
user program.
(4
) Subsystem clock
The clock settings are listed below.
(a) When the clock generated within the emulator is used
This method uses the clock inside the emulator by configuring the use of the subsystem clock in the user
program. For debugger settings, check the user's manual for the debugger that will be used.
(b) When the clock (a square wave) is supplied from the target system
Select the "External" in the debugger. The clock input from the target system is then used.
Oscillation with the resonator on the target system is not supported. To input a clock from the target system,
input to the clock pin (XT2) the square-wave signal with the same voltage potential as that of the target
device supply voltage (V
The selectable frequencies are same as those of the target device.
