3.3 Selecting Clock Supply

There are two ways to supply a clock to the MCU, using the oscillator circuit of the emulation pod
or using the oscillator circuit on the target system. Table 3.2 shows the factory-settings of each clock
supply.

IMPORTANT

Note on Changing the Clock Supply:

• For using P31/XCIN pin as a sub-clock, it is necessary to set the SW1 in the

emulation pod to XCIN side. For how to set the switches, refer to "3.2 Switch
Settings" (page 23).

• The clock supply of XIN-XOUT and XCIN-XCOUT pins can be set by the Init

dialog when starting up the emulator debugger or inputting CLK command on the
script window. The examples of CLK command are below.

Example 1. When selecting the internal oscillator circuit of the emulation pod

CLK INT,INT

Example 2. When selecting the oscillator circuit on the target system

CLK EXT,EXT
