Programmable angle sensor
Figure 14
shows the coding of a single bit with a HIGH level of V
IH
and a LOW level of V
IL
.
Here the pulse width t
w1
or t
w0
represents a logic 1 or a logic 0 of a full bit period T
bit
,
respectively.
13.3 Sending and receiving data
The master has to control the communication during sending or receiving data.
The command byte defines the region, address and type of command requested by the
master. In case of a read command, an additional handover or takeover bit must be
inserted before and after the two data bytes (see
Figure 12
). However the OWI is a serial
data transmission, whereas the Most Significant Byte (MSB) must be sent at first.
