Commands
STFPC320
34/78
The first byte after the configuration command is in the following format:
Figure 14.
First byte format after configuration byte
When b7 = ‘0’, incoming RC data is output on SDA in decoded format where the Device
Address, Start Bit, Toggle Bit and Data Bits are sent. Note that the default location is 0x00
for the first device address. This order of the bits sent is in the same format as the incoming
RC data.
When b7 = ‘1’, incoming raw data (no header information) is output on SDA.Address
decoding is still performed to decode the corresponding RC protocol. The format of the data
on SDA corresponds to the format of the respective RC frame.
For details, refer to the RC protocol section of the datasheet.
Upon power application, the following modes are selected:
●
Normal display setting: 16-digit, 12-segment mode is selected (default: display off and
keyscan on).
●
Remote control protocol setting: RC-5 with raw format.
●
Guard timer setting: turned on with 10s. After the first command is processed by
STFPC320, the guard timer is turned off until it is turned on by the host.
●
Guard timer action: issue standby.
