DRV_SST39_PageWrite Function

bool DRV_SST39_PageWrite( const DRV_HANDLE handle, void *tx_data, uint32_t address )

Writes one page of data starting at the specified address.

This function schedules a blocking write operation for writing maximum one page of data into flash memory.

The DRV_SST39_Open() routine must have been called for the specified SST39 driver instance.

The flash address location which has to be written, must have been erased before using the SST39_xxxErase() routine.

The flash address has to be a Page aligned address.

• true

  • If the write request is successfully sent to the flash

• false

  • If Write enable fails before sending sector erase command to flash

  • If write command itself fails
