command phase indicates whether or not the MTP memory shall be able to service the read request. If it
is possible to carry out the read, the FT1248 moves into the data phase where it can either continue with
the read transaction until the slave successfully returns an ACK along with the data or if it receives NAK
during the data phase it can abort the read transfer and try again. When the read has been serviced the
