Fast Read Single Block
On receiving the Fast Read Single Block command, the M24LR64-R reads the requested
block and sends back its 32-bit value in the response. The Option_flag is supported. The
data rate of the response is multiplied by 2.
The Protocol_extention_flag should be set to 1 for the M24LR64-R to operate correctly. If
the Protocol_extention_flag is at 0, the M24LR64-R answers with an error code.
