2.1

Software Settings

Check the user's manual for the debugger that will be used.

2.2

Clock Settings

The QB-RL78L1C clock must be set to the clock used by the target device. For details about how to set the clock,

check the user's manual for the debugger that will be used.

QB-RL78L1C clock settings for the clock used by the target device are shown below.

Oscillation with the resonator on the target system is not supported.

Therefore, the in-circuit emulator cannot

emulate the oscillation operation of the clock on the target system.

Table 2-1.

List of clock settings

Clock Used

Clock Supply

(1) High-speed system clock

(X1 oscillator or External input)

(a) When the clock generated within the emulator is used

(b) When the clock (a square wave) is supplied from the

target system

is used

(2) Internal high-speed

oscillation clock

Uses the clock internally generated from the emulator

(3) Internal low-speed

oscillation clock

Uses the clock internally generated from the emulator

(4) Subsystem clock

(XT1 oscillator or External

input)

(a) When the clock generated within the emulator is used

(b) When the clock (a square wave) is supplied from the

target system
