Transfer Mode | |
|
This determines whether the driver operates synchronously or asynchronously In MCSPI_TRANSFER_MODE_BLOCKING mode MCSPI_transfer() blocks code execution until the transaction has completed In MCSPI_TRANSFER_MODE_CALLBACK MCSPI_transfer() does not block code execution and instead calls a MCSPI_CallbackFxn callback function when the transaction has completed | |
| #define | MCSPI_TRANSFER_MODE_BLOCKING (0U) |
| MCSPI_transfer() blocks execution. This mode can only be used when called within a Task context More... | |
| #define | MCSPI_TRANSFER_MODE_CALLBACK (1U) |
| MCSPI_transfer() does not block code execution and will call a MCSPI_CallbackFxn. This mode can be used in a Task, Swi, or Hwi context More... | |
| typedef void(* | MCSPI_CallbackFxn) (MCSPI_Handle handle, MCSPI_Transaction *transaction) |
