| Version: V 1.4 |
| Initial Editor: Thomas Lang |
+-----------------------------------------------------------------------------+
| Description: |
| This file contains the declarations, required for use of the SPC3 with |
| DPS2-Interface. |
| |
| Before #include "SPC3DPS2.H" must be defined: |
| #define SPC3_INTEL_MODE !=0: Intel-Interface |
| ==0: Motorola-Interface |
| |
| ======================== for SAB C165: ================================ |
| #define SPC3_FAR if the SPC3 is located in FAR-address space |
| #define SPC3_NEAR if the SPC3 is located in NEAR-address space |
| |
| ======================= for iNTEL 8032: =============================== |
| #define SPC3_DATA_XDATA if user-data in xdata-space |
| #define SPC3_DATA_IDATA if user-data in idata-space |
| else generic pointers are used |
| |
| =========================== general =================================== |
| Before #include "SPC3DPS2.H" may be defined: |
| #define SPC3_NO_BASE_TYPES: The types UBYTE, UWORD, BYTE and WORD will |
| not be declared |
| |
+-----------------------------------------------------------------------------+
| following environments are supported |
| Processor: SAB C165 |
| Compiler: BSO Tasking 80166 C Cross-Compiler, V 4.0 |
| Processor: iNTEL 8032 |
