Functions | |
| Void | ACPY3_configure (IDMA3_Handle handle, ACPY3_Params *params, short transferNo) |
| Functions called by the framework for allocating and initializing the channel state. | |
| Void | ACPY3_fastConfigure16b (IDMA3_Handle handle, ACPY3_ParamField16b fieldId, unsigned short value, short transferNo) |
| Modify the 16-bit DMA transfer parameter, indicated by the parameter field id, fieldId, of the current channel settings. | |
| Void | ACPY3_fastConfigure32b (IDMA3_Handle handle, ACPY3_ParamField32b fieldId, Uns value, short transferNo) |
| Modify the 32-bit DMA transfer parameter, indicated by the parameter field id, fieldId, of the current channel settings. | |
| Void | ACPY3_setFinal (IDMA3_Handle handle, short transferNo) |
| Indicate that a given transfer will be the last in a sequence of linked transfers. | |
| Void | ACPY3_fastSetFinal (IDMA3_Handle handle, short transferNo) |
| Indicate that a given transfer will be the last in a sequence of linked transfers. | |
| Void | ACPY3_start (IDMA3_Handle handle) |
| Submit a single or linked transfer using the most recently configured transfer parameter settings. | |
| Void | ACPY3_wait (IDMA3_Handle handle) |
| Wait for all data transfers on a logical channel to complete. | |
| Void | ACPY3_waitLinked (IDMA3_Handle handle, unsigned short waitId) |
| Wait for an individual transfer in a Linked transfer to finish. | |
| Bool | ACPY3_complete (IDMA3_Handle handle) |
| Check to see if all dma transfers on logical channel are finished. | |
| Bool | ACPY3_completeLinked (IDMA3_Handle handle, unsigned short waitId) |
| Non-blocking query to check completion of an individual transfer in a Linked transfer. | |
| Void | ACPY3_activate (IDMA3_Handle handle) |
| Activate the given channel. | |
| Void | ACPY3_deactivate (IDMA3_Handle handle) |
| Deactivates the given channel. | |
| Void | ACPY3_init (Void) |
| Initialize the ACPY3 module. Called by framework. | |
| Void | ACPY3_exit (Void) |
| Finalization of the ACPY3 module. | |
Defines | |
| #define | ACPY3_GTNAME "ti.sdo.fc.acpy3" |
| #define | ACPY3_MODNAME "ti.sdo.fc.acpy3" |
| Name to pass to Diags_setMask() to enable logging for ACPY3 functions. For example, Diags_setMask(ACPY3_MODNAME"+EX1234567"); turns on all Log statements in this module. Diags_setMask() must be called after initialization to take effect. | |
