Figure 10 shows the different modes of iC-MP. There
are two major modes of operation:

Normal Mode:
Readout position data and error bit. Normal mode is
subdivided into two minor modes of operation:
– Fast Scanning Mode:
iC-MP is always activated.
– Slow Scanning Mode (Power Save Mode):
iC-MP goes into Slow Mode Sleep following the
first transmission of sensor data via the serial
interface.
•
Programming Mode:
iC-MP can be configured in programming mode. See
the chapter on ’PROGRAMMING MODE’ for further
details. There are three minor modes:
– Read ROM:
iC-MP’s Zener zap ROM structure is read.
– Write RAM:
iC-MP’s internal registers can be temporarily
programmed for test purposes.
– Write ROM:
iC-MP’s zapping structure is programmed.
A Power-On Reset is required after a Read ROM and
Write ROM instruction. Each state is quit by a Power-
On Reset.
