Si3050 + Si3011/18/19
5.40. Summary of Monitor Channel Commands
Communication with the Si3050 should be in the following format:
Byte 1: Device Address Byte
Byte 2: Command Byte
Byte 3: Register Address Byte
Bytes 4-n: Data Bytes
Bytes n+1, n+2: EOM
5.41. Device Address Byte
The Device Address byte identifies which device connected to the GCI highway receives the particular message.
This address should be the first byte sent to the Si3050 at the beginning of every transmission sequence. For Read
commands, the address sent to the Si3050 is the first byte transmitted in response to the Read command before
register data is transmitted. This Device Address byte has the following structure:
The lowest programmable bit, C, has a special function. This bit enables a register read or write, or enables a
special Channel Identification Command (CID).
C = 1: Normal command follows.
C = 0: Channel Identification Command.
The CID is a special command to identify themselves by software. For this special command, the subsequent
command byte transmitted by the host processor must be $00 (binary), and have no address or data bytes. The
Si3050 in turn responds with a fixed 2-byte identification code:
Upon sending the 2-byte identification code, the Si3050 sends an EOM (MR = MX = 1) for two consecutive frames.
When A = 0, B must be 0 or the Si3050 signals an abort due to an invalid command. In this mode, bit C is the only
other programmable bit.
A = 0: Response to CID command from the device using channel B1 is placed in Monitor Data.
