RC7108

Operation
The RC7108 is programmed by writing 10 bytes
of eight bits each. See Table 3 for byte order.

Byte Description
Commands the RC7108 to accept the bits in Data Bytes 3-6 for internal
register configuration. Since other devices may exist on the same
common serial data bus, it is necessary to have a specific slave address
for each potential receiver. The slave receiver address for the RC7108
is 11010010. Register setting will not be made if the Slave Address is
not correct (or is for an alternate slave receiver).
Unused by the RC7108, therefore bit values are ignored (don’t care).
This byte must be included in the data write sequence to maintain
proper byte allocation. The Command Code Byte is part of the standard
serial communication protocol and may be used when writing to another
addressed slave receiver on the serial data bus.

This byte must be included in the data write sequence to maintain
proper byte allocation. The Byte Count Byte is part of the standard serial
communication protocol and may be used when writing to another
addressed slave receiver on the serial data bus.
The data bits in these bytes set internal RC7108 registers that control
device operation. The data bits are only accepted when the Address
Byte bit sequence is 11010010, as noted above. For description of bit
control functions, refer to Table 4, Data Byte Serial Configuration Map.
