Remote control protocols

STFPC320

62/78

15.7.1

R2000 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 the R2000 protocol, if the 4-bit ADR is “1101” and 7-bit command bits is “1010100”, the

in decoded format the data on SDA pin will be sent as follows with MSB transmitted first.

15.7.2

R2000 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. So for the above example for R2000

protocol, the data on SDA pin in raw-format will be as in Figure 42.
