Data Sheet
20.2.3
The INCA-D can be adapted to various external hardware configurations by a special
register: PIDDHWCFG. This register is written once during initialization and must not be
changed while the INCA-D is in active mode.
20.3
There are some restrictions concerning the modules that can be enabled at the same
time (Table 20-32). A cell marked with ’X’ indicates that the two modules (defined by the
row and the column of the cell) must not be enabled at the same time.
The freely configurable noise reduction unit (Section 20.1.10) has some additional
restrictions which are not stated in Table 20-32. Even if the noise reduction can be used,
some limitations for the filter length of the echo cancellation unit exist. A detailed
description of these restrictions is provided with the register description of register
NRCTL.
