4.4.3 SIM40 Example Configuration Code
The following code is an example configuration sequence for the SIM40 module.
***************************************************************************
* MC68340 basic SIM40 register initialization example code:
* This code is used to initialize the MC68340's internal SIM40 registers,
* providing basic functions for operation.
* It includes chip select programming for external devices.
* This code would be programmed beginning at offset $0 into ROM which is
* relocated to address $60000 by the initialization code.
* The SSP_VEC and RST_VEC vectors used to initialize the system stack
* pointer and initial PC, respectively, are located at offset $0 after
* reset.
