int sf_readDeviceRAM( sf_device * dev, long buffer, int offset, int len, int flags );

Description

Read data from the RAM buffer on the serial flash chip into an xmem buffer.

Parameters

dev

Pointer to sf_device struct for initialized flash device.

buffer

Address of an xmem buffer.

offset

The address in the serial flash RAM to start reading from.

len

The number of bytes to read.

flags

Can be one of the following:

SF_BITSREVERSED - Reads the data in bit reversed order from the flash chip. This improves speed, but the data must have been also written in reversed order (see sf_XWriteRAM)

SF_RAMBANK1(default) - Reads from the first RAM bank on the flash device

SF_RAMBANK2 - Reads from the alternate RAM bank on the flash device
