Programming Overview
The transmission characteristics and interfaces of the PEB 2466 can be adapted to
various environments. Configuring the functional blocks and programming the digital
filter behavior is accomplished by loading values to the Configuration Registers and the
Coefficient RAM (CRAM). Software utilities are available to determine the appropriate
register and CRAM values (see
Programmer’s Reference Manual
).
6.1
Programming Overview
The SICOFI
4-μC has eight Common Configuration Registers (XR0 to XR7). Settings in
these registers affect all four channels.
Each of the four channels has six Channel-Specific Configuration Registers (CR0 to
CR5). Settings in these registers affect only the designated channel.
The filters of each channel are individually programmable through channel-specific
coefficients in CRAM. There are four global sets of TH Filter coefficients that can be
assigned to any channel.
