| Description | The PECDEF directive reserves memory space required by the PEC source and destination pointers for the specified channels. The PEC source and destination pointers are used for PEC transfers and are located in internal RAM at address 0FDE0h-0FDFFh. By default, this memory is available to the application program. | |
| Example |
C166 SAMPLE.C PECDEF (0, 2, 4) // Reserve memory for PEC channel 6 #pragma PD (6) // Reserve memory for PEC channels 1-7 #pragma PD (1, 2, 3, 4, 5, 6, 7) // Reserve memory for PEC channels 1-3 and 5-7 #pragma PD (1 - 3, 5 - 7) |
