1.8.1 Integrated BDM
The DEMO9S08AC60E features an integrated
The integrated debugger provides the DEMO9S08AC60E with power eliminating the need to power the board externally. Power is derived from the USB bus, therefore total current consumption should not exceed 500mA. Excessive current drain will violate the USB spec and damage to your Host PC’s USB hub or the DEMO9S08AC60E could occur.
1.8.2 BDM Header
J32 is the stand alone BDM header. Use of this port requires the user to solder a 2 x 6 100 mil center header on the board. The pinout is as follows:
