2.108 Serial Quad Interface (SQI)
This Plib implements software abstraction for SQI Peripheral.
Library Interface
SQI peripheral library provides the following interfaces:
Functions
| Name | Description |
|---|---|
| SQIx_Initialize | Initializes given instance of the SQI peripheral |
| SQIx_DMASetup | Sets up SQI peripheral to DMA mode |
| SQIx_DMATransfer | Starts a DMA transfer to the SQI slave device |
| SQIx_XIPSetup | Sets up SQI peripheral to XIP mode |
| SQIx_RegisterCallback | Sets the pointer to the function (and it's context) to be called when the operation is complete |
Data types and constants
| Name | Type | Description |
|---|---|---|
| SQI_EVENT_HANDLER | Typedef | Defines the data type and function signature for the SQI peripheral event handler function |
| SQI_LANE_MODE | Enum | Defines the data type to specify the type of lane |
| SQI_XIP_ADDR_BYTES | Enum | Defines the data type to specify the number of address bytes |
| SQI_XIP_DEV_SELECT | Enum | Defines the data type to specify the device to be used |
| sqi_dma_desc_t | Struct | Defines the data type for the SQI DMA based transfer |
Note: Not all APIs maybe implemented. See the specific device family
section for available APIs.
