CONFIGURATION PARAMETERS
Register Map
The iC-TW28 contains two types of registers, static and
dynamic, as shown in Table 28 and Table 29. Static
registers are not changed or updated by the iC-TW28
during operation. Static registers generally contain con-
figuration data and their values are saved in the internal
EEPROM and restored after each startup. Static reg-
isters may be read or written using the SPI port or the
Encoder Link interface. Reserved bits in static registers
must be zero for proper operation, as shown.
Dynamic registers are updated by the iC-TW28 during
operation or auto calibration to reflect current operat-
ing conditions or status. In general, dynamic registers
are read-only, but the correction value registers can
be written and startup values are stored in the internal
EEPROM. Dynamic registers may be read via the SPI
port or the Encoder Link interface. Reserved bits in
dynamic registers are undefined.
Registers not shown are reserved and must not be ac-
cessed. Changes to static register values take effect
immediately.
