/*****************************************************************************
Function:
void SPIFlashWriteArray(BYTE* vData, WORD wLen)
Summary:
Writes an array of bytes to the SPI Flash part.
Description:
This function writes an array of bytes to the SPI Flash part. When the
address pointer crosses a sector boundary (and has more data to write),
the next sector will automatically be erased. If the current address
pointer indicates an address that is not a sector boundary and is not
already erased, the chip will silently ignore the write command until the
next sector boundary is crossed.
Precondition:
SPIFlashInit and SPIFlashBeginWrite have been called, and the current
address is either the front of a sector or has already been erased.
Parameters:
vData - The array to write to the next memory location
wLen - The length of the data to be written
Returns:
None
Remarks:
See Remarks in SPIFlashBeginWrite for important information about Flash
memory parts.
