User’s Manual
– Channelwise external loop
– Channelwise internal loop
See Chapter 5.1 and Chapter 5.3.2 for a more detailed discussion of test loops.
All loops of the MUNICH32 V3.2 are under complete software control. Loops can be
closed and opened via software.
Handling of the MUNICH32 V3.2 loops:
Switch loops on:
RES = IN = ICO = ‘0’
LOC, LOOP, LOOPI
PCM, MFL, IM, IA
CHANNEL NUMBER
Switch loops off:
RES = IN = ICO = ‘0’
LOC = ‘0’, LOOP = LOOPI = ‘1’
PCM, MFL, IM, IA
CHANNEL NUMBER
IA:
One single logical channel is mirrored logically from serial data input to serial data
output. The other channels are not affected by this operation. The data rate for this
single logical channel has to be identical for receive and transmit direction.

Interrupt Attention; a new interrupt queue is defined by the host. MUNICH32 reads
the interrupt queue specification and writes the interrupt information into the new
interrupt queue.
for selected loop type
don’t change the previous values
in case of channelwise loops use the selected
channel number
in case of complete loops use channel number of an
active channel.
don’t change the previous values
use channel number used with the ‘switch loop on’.
