Initiate
On receiving the Initiate command, the M24LR64-R will set the internal Initiate_flag and
send back a response only if it is in the ready state. The command has to be issued in the
Non Addressed mode only (Select_flag is reset to 0 and Address_flag is reset to 0). If an
error occurs, the M24LR64-R does not generate any answer. The Initiate_flag is reset after
a power off of the M24LR64-R.
