The following example shows how subchannel processing can be configured by the HDLC_PAR
register.
Example:
CHANNEL 0
CHANNEL 1
Figure 7: Example for Subchannel Processing
The start bit can be selected by bits 5..3 of the HDLC_PAR register. The number of bits to process can
be selected by bits 2..0 of the HDLC_PAR register. By default (HDLC_PAR = 00h) all 8 bits are
processed. In the given example the start bit is bit 2 and the number of bits to process is 3. The not
processed bits are set to the value given in the CH_MASK register. Please note that the HDLC_PAR
register settings can be different for each channel.
