Table 13.
Where T = 0.436ms
Note that the above waveform is on the transmitted side. The received data by the
STFPC320 after the photo-diode is inverted from above.
Matsushita in decoded format
In the decoded form, the ADR bits followed by Start bit and Toggle Bit followed by Data bits
are sent in this order for each remote control protocol. The number of bits depends on the
corresponding RC protocol. The remaining empty bits are stuffed with 1’s to complete a
byte-aligned data frame.
For Matsushita protocol, if the 5-bit custom code is “11000” and 6-bit data code is “101010”,
the in decoded format the data on SDA pin will be sent as follows with MSB transmitted first
