6 Working with HCS08 Devices
6.1 Communication Settings
inDART-One must be configured properly so that BDM communication with
the target device can be established correctly.
Communication settings are defined through the “Communication Settings”
dialog box, available both in CodeWarrior and in the DataBlaze and
MultiBlaze programming utilities.

6.1.1 BDM Clock
The BDM communication speed depends on a clock source which, in turn, is
selected by the CLKSW bit in the Status register. If the CLKSW bit is set to
1, the BDM communication clock source is the microcontroller’s bus
frequency; if the CLKSW bit is set to 0, the BDM communication clock
source is a constant clock source, which can vary depending on the specific
HCS08 derivative. In the case of the MC9S08GB60, for example, this
constant clock source is a 8 MHz internal clock. Other derivatives may use
the external crystal frequency.
Which CLKSW setting to use depends on the target system and on the user
application. The idea is to set the CLKSW bit so that the highest (and less
subject to changes) clock frequency is used for the BDM communication. A
