Page 16: Circuit Description
HC08 Welcome Kit 6. Circuit Description Schematic Diagram The schematic diagram of the HC08 Welcome Kit is available as a separate document to ensure optimum visibility of all details. Controller Core and Input/Output The Microcontroller HC908GP32 needs only a few external components. -
Page 17: Clock Generation
PLL mode, the "canned" oscillator IC3 must be removed and solder bridge BR4 must be closed. The HC08 Welcome Kit is shipped with the High-Speed Flash Loader FL08 residing in Flash memory. FL08 uses the PLL to generate a bus clock of 7.3728 MHz. - Page 18 HC08 Welcome Kit pins must be connected to certain logic levels, as summarized in the following table: Port Level PTA0 PTA7 PTC0 PTC1 PTC3 Monitor Mode Levels on Ports A and C The monitor mode interface circuit on the evaluation board produces these levels using five pull up or pull down resistors.

Page 19: User Rs232 Port
HC08 Welcome Kit board represents the device side. The reverse case happens if a serial LC display is to be operated at the user RS232 port. In this configuration, the HC08 Welcome Kit board is the host and the LCD module represents the device side. The necessary RxD/TxD crossing can be done externally or by setting the solder bridges BR1/BR2 to position 2-3. -
Page 20: Application Hints
7. Application Hints In this section some details will be given on how to program the HC908GP32 in general and the HC08 Welcome Kit in particular. Please be aware that, even if this manual can provide some specific hints, it is impossible to cover all kinds of knowledge and techniques required to design a microcontroller program.
