5.1.7 Read Buffer – E4h
This command enables the host to read the current contents of the device’s sector buffer. When this
command is issued, the device sets the BSY bit, enables the sector buffer for a read operation, sets
the DRQ bit, clears the BSY bit, and generates an interrupt. The host then reads the data from the
buffer.
