to set the target configuration of MODEA and RPL.
After that the command SWITCH is executed. By
reading STATUS1 it is possible to control if there was
an error while executing the command. After the
next startup or after the execution of the command
SOFT_RESET iC-MU starts with the interface config-
urated with MODEA_NEW and RPL_NEW.
Direct Communication To Multiturn Sensor
Making use of the BiSS Interface bus capabilities, iC-
MU can connect in modes MODEA = 0x02 and 0x04-
0x07 (BiSS and SSI) the external multiturn sensor to
the BiSS master controller when GET_MT is enabled.
To this end pin MA (PA1) receiving the BiSS master’s
clock signal is fed through to pin MTC and the MTD
pin is activated in place of the SLI (PA2) pin. Upon en-
abling this mode the single cycle timeout must have
elapsed and an additional init command carried out
by the BiSS master, before it can run the first register
communication.
Example: external multiturn sensor built with iC-MU is
connected to the MT interface of a first iC-MU, prepar-
ing the singleturn data. With GET_MT enabled, the
external multiturn can then be addressed via BiSS ID
0 and the singleturn via BiSS ID 1. This temporal chain
operation simplifies device parametrization during en-
coder manufacturing.
