(Read only once after each action request pulse with an action specification with set IN
or RES bit)
The time slot assignment provides the cross reference between the 32 (24) time slots of
the PCM highway and the data channels (up to a maximum number of 32). The data
channels can be composed of different receive and transmit time slots, which have
individual bit rates. With the concept of subchanneling, MUNICH32 can realize flexible
transmission from 8 kbit/s up to 2.048 Mbit/s per channel.

For bit rate adaption the fill/mask code determines the number of bits
and the position of these bits within the time slot. For all modes
except TMA the bits selected by Fill/Mask = 1 in the slots of a channel
are concatenated, those with Fill/Mask = 0 are ignored/tristated in
receive/transmit direction. For TMA the bits with Fill/Mask = 0 are
received as ‘1’-bits, in transmit direction these bits are overwritten
with ‘Z’ (see Chapter 2.4 for more details).
