preliminary
CONFIGURABLE I/O INTERFACE
Rev B1, Page 25/59
Setting the interfaces
iC-MU has several configurable output modes which
can be set using parameters MODEA and MODEB.
The pins at port A are set with MODEA. The choice
of a serial interface at port A has also effect on the out-
put of error and warning bits in the serial protocol see
Table 31.
N.B.:
With an empty EEPROM or after the third faulty at-
tempt to read-in the configuration data from the EEP-
ROM the default value of MODEA is set to BiSS or
SPI depending on the logic level at pin PA0 (PA0=0
→ BiSS, PA0=1 → SPI).

N.B.:
It is not possible to select ABZ at port A and ABZ,
Step/Direction or CW/CCW at port B simultaneously.
In operating modes ABZ, UVW, step/direction, and
CW/CCW the position is output incrementally. In set-
ting SIN/COS Master the master track analog signal is
switched directly to the analog drivers. The signals of
the nonius track are available on the drivers with set-
ting SIN/COS Nonius.
