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-MU150 starts with the interface configurated with

MODEA_NEW and RPL_NEW.

MT Interface Daisy Chain

The MT interface daisy chain mode gives direct access

to an external multiturn sensor for calibration purposes.

MODEA

Code

0x2

0x5

0x6

0x7

Function

BiSS

SSI+ERRL

SSI+ERRH

ExtSSI

configuration

To this end input pin MA (PA1) receiving the BiSS mas-

terâs clock signal is fed through to output pin MTC and

the input pin MTD is activated in place of the input pin

SLI (PA2). Upon enabling this mode the single cycle

timeout (see Fig. 3) must have elapsed and an ad-

ditional init command carried out by the BiSS master,

before it can run the first register communication.

Note:

Additional condition RSSI = 1 when using GET_MT

and MODEA = 0x05, 0x06 or 0x07.

Hint:

First set GET_MT than RSSI to activate direct com-

munication to Multiturn Sensor in SSI modes.

Example: external multiturn sensor built with iC-MU150

is connected to the MT interface of a first iC-MU150,

preparing 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

encoder manufacturing.

Making use of the BiSS Interface bus capabilities,

iC-MU150 can connect the external multiturn sensor to

the BiSS master controller in modes MODEA = 0x02

(BiSS) and MODEA = 0x05-0x07 (SSI with Error bit and

ExtSSI; additional condition RSSI = 1) when GET_MT

is enabled.
