Matsushita in RAW format

In the raw form, the data is sent in the same way as it is received for each RC protocol

except that the header is not transmitted on SDA. If a valid SYN pulse is detected, it is

represented by a bit ‘1’. So a first bit with value ‘1’ implies that the data following it is a valid

raw format RC data. So for the above example for Matsushita protocol, the data on SDA pin

in raw-format will be as in Figure 39.
