IN:
ICO: Initialize Channel Only; only the channel specification of the selected channel
IM:
RES: RESET; a single initialization procedure is performed. The time slot assignment
Note 1: The bits IN, ICO, RES are mutually exclusive within one action specification.
For test purposes four different loops can be switched at the serial interface with aid of
LOC, LOOP, LOOPI according to the following table

The loops have the following functions:
– Complete external loop
– Complete internal loop
User’s Manual
The serial data input is physically mirrored back to the serial data output. The time and
strobe signals for receive and transmit direction have to be identical.
The serial data output is physically mirrored back to the serial data input. The data on
the external input line are ignored. The logical channels have to be programmed
identically. The time and strobe signals for receive and transmit direction have to be
identical.
Initialization procedure; setting this bit to one causes MUNICH32 to fetch all the
time slot assignments and the channel specification of the selected channel
(channel number). To avoid collision all time slots being reinitialized should be in
a deactivated mode, i.e. the receive and transmit channels must be switched off.
(channel number) is read and reconfigured.
Interrupt Mask; MUNICH32 suppresses the interrupt normally generated in order
to acknowledge the action request.
and all channel specifications are written into the CSR. All time slots are
reinitialized.
They establish different ways of initializing, configuring and reconfiguring the
channels and time slots of the MUNICH32.
