Field Documentation

◆ handle

OSPI_Handle OSPI_Object::handle

Instance handle

◆ transferMode

uint32_t OSPI_Object::transferMode

Polling, Blocking or Callback mode. Refer OSPI_TransferMode

◆ xferLines

uint32_t OSPI_Object::xferLines

Number of lines used for OSPI reading/writing

◆ rdDummyCycles

uint32_t OSPI_Object::rdDummyCycles

Number of dummy cycles needed for read

◆ cmdDummyCycles

uint32_t OSPI_Object::cmdDummyCycles

Number of dummy cycles needed for cmd

◆ rdDataCapDelay

uint32_t OSPI_Object::rdDataCapDelay

Read data capture delays needed

◆ phyRdDataCapDelay

uint32_t OSPI_Object::phyRdDataCapDelay

Read data capture delays needed when phy is enabled

◆ numAddrBytes

uint32_t OSPI_Object::numAddrBytes

Number of bytes used to represent address to be sent to flash. This is the actual number of bytes used. The code to be programmed to registers is this value-1. That is, for 4-byte addressing mode, register should be programmed as 3

◆ cmdExtType

uint32_t OSPI_Object::cmdExtType

In dual byte opcode mode, the extended opcode can vary depending on flash This variable should be populated from the flash driver using the OSPI_setCmdExtType API

◆ isOpen

uint32_t OSPI_Object::isOpen

Flag to indicate if the instance is already open

◆ lockObj

SemaphoreP_Object OSPI_Object::lockObj

Driver lock object

◆ transferSemObj

SemaphoreP_Object OSPI_Object::transferSemObj

Transfer Sync Semaphore object

◆ hwiObj

HwiP_Object OSPI_Object::hwiObj

Interrupt object

◆ phyEnableSuccess

uint32_t OSPI_Object::phyEnableSuccess

This has to be set from the flash driver if the PHY tuning completed successfully

◆ currTrans

OSPI_Transaction* OSPI_Object::currTrans

Pointer to current transaction struct

◆ ospiDmaHandle

void* OSPI_Object::ospiDmaHandle
