* Power Up and Hardware Reset (RST) Value = 00h.
The B Filter is disabled during receive cutoff.
73h Read Revision Code Number (RCN)
This command returns an 8-bit number (RCN) describing the revision number of the QLSLAC device. The revision code of the
QLSLAC device will be 14h or higher. This command does not depend on the state of the Channel Enable Register.
80/81h Write/Read GX Filter Coefficients
Cxy = 0 or 1 in the command above corresponds to Cxy = +1 or −1, respectively, in the equation below.
The coefficient for the GX filter is defined as:
Power Up and Hardware Reset (RST) Values = A9F0 (Hex) (H
Note:
The default value is contained in a ROM register separate from the programmable coefficient RAM. There is a filter enable bit in Operating Func-
tions Register to switch between the default and programmed values.
