In Simple Mode (SM) the CHANNEL number is the same as the FIFO number. If Channel Select
Mode (CSM) is enabled the transmit CHANNEL for a FIFO can be selected by
Please note that receive CHANNELs are odd numbered (bit 0 of CHANNEL# register = '1').
The bit values of the not processed bits of the receive CHANNEL are ignored. The processed
bits are taken from the CHANNEL (see also: Subchannel Processing). Please note that more than
one FIFO can receive data from the same CHANNEL (e.g. bits 1..0 are processed by FIFO 1 and
bits 3..2 by FIFO 3). This is useful to split subchannels that have been combined to be
transmitted in one ISDN channel.
Data can either be received from the S/T interface or the PCM interface.
The CON_HDLC register bits 7..5 settings must be the same for corresponding receive and
transmit FIFOs.
A PCM SLOT can be connected to a CHANNEL.
The PCM SLOT number for a FIFO can be selected by writing the desired SLOT number to its
timeslot selection register shown in the table above. Please note that only the *_RSL registers are
for receive slots.

1) writing the FIFO number (0..7) in the FIFO# register
2) writing the desired CHANNEL number (0..7) to the CHANNEL# register (bits 2..0)
1) write the FIFO number (0..7) in the FIFO# register
2) write the desired connection to the CON_HDLC register bits 7..5
