Serial Interface Mode
In the Serial I/F Mode, the ML9044 interfaces with the CPU via the
CS
,
SHT
, SI and SO pins.
Writing and reading operations are executed in units of 16 bits after the
CS
signal falls down. If
the
CS
signal rises up before the completion of 16–bit unit access, this access is ignored.
When the BF bit is “1”, the ML9044 cannot accept any other instructions. Before inputting a new
instruction, check that the BF bit is “0”. Any access when the BF bit is “1” is ignored.
Data format is LSB–first.
