eighth bit of the address is the R/W bit. If the operation is a write, the next byte is the Memory Address Point-
er (MAP) which selects the register to be read or written. If the operation is a read, the contents of the reg-
ister pointed to by the MAP will be output. Setting the auto increment bit in MAP allows successive reads or
writes of consecutive registers. Each byte is separated by an acknowledge bit. The ACK bit is output from
the
Since the read operation cannot set the MAP, an aborted write operation is used as a preamble. As shown
in
dition. The following pseudocode illustrates an aborted write operation followed by a read operation.
Setting the auto increment bit in the MAP allows successive reads or writes of consecutive registers. Each
byte is separated by an acknowledge bit.
