6.1 The Data Transmission Driver

Data is transferred between the simulated peripheral registers and the ST626x registers via

the host PC’s parallel port. The DEMOK65.HEX program, with which the ST6265 microcon-

troller that is plugged into the Starter Kit board must be loaded includes the transmission driv-

er.

The data transfer driver uses the following bits:

Note: Do not connect any external resources to the corresponding J2 connector pins when us-

ing the Starter Kit board as a peripheral emulator.

6.2 Technical Limitations

The Starter Kit board has the following limitations when used with WGDB6 as a hardware sim-

ulator:

• Real-time program execution is not supported.

• Resetting the ST6265 by power on, pressing the Reset button or external reset does not

• Interrupts sent by the ST6265 microcontroller are not supported by the WGDB6 simulator.

• The pins: NMI, PA0, PA1 and PA2 on the ST6265 microcontroller are used for communica-

• You cannot modify the D0, D1 and D2 bits of the DDRA, ORA and DRA registers.
