Open() - NOR Flash Driver

void  Open (FS_DEV_NOR_PHY_DATA  *p_phy_data,

            FS_ERR               *p_err);

File	Called from	Code enabled by
NOR physical-layer driver	`FSDev_NOR_Open()`	N/A

Open (initialize) a NOR device instance and get NOR device information.

p_phy_data

Pointer to NOR phy data.

p_err

Pointer to variable that will receive the return error code from this function.

None.

Several members of p_phy_data may need to be used/assigned:

BlkCnt and BlkSize must be assigned the block count and block size of the device, respectively.
RegionNbr specifies the block region that will be used. AddrRegionStart must be assigned the start address of this block region.
DataPtr may store a pointer to any driver-specific data.
UnitNbr is the unit number of the NOR device.
MaxClkFreq specifies the maximum SPI clock frequency.
BusWIdth, BusWidthMax and PhyDevCnt specify the bus configuration. AddrBase specifies the base address of the NOR flash memory.
