COP (Coefficient Operation) Command
The COP command, which is a GCI command, writes or reads data related to filter coefficients. Filter coefficient data is used by
the voice processors within the QLSLAC device to configure the various filters in the voice channel. In this case, 1 to 14 coefficient
bytes follow the command byte. The QLSLAC device interprets the bytes as canonic signed digital (CSD) data and sets the
coefficients accordingly.
The QLSLAC device responds to the read coefficient command by sending up to 14 CSD bytes upstream. These bytes contain
the coefficients requested by the upstream controller. For diagnostic purposes, various RAM locations containing data to which
the QLSLAC device has access can also be read back by this command.
The generic transmission sequence for the COP command is shown in Table
The following tables show the format of the COP bytes that follow a downstream address byte.
