The KMA199 provides an OWI to enable programming of the device which uses
pin OUT/DATA bidirectionally.
In general the device runs in analog output mode, the normal operating mode. This mode
is configured by the embedded programming data and is started after a power-on reset
once time t
corresponding output voltage.
Command mode has to be entered to enable programming. In this mode, the customer
can adjust all required parameters (for example zero angle and angular range) to meet the
application requirements. After enabling the internal charge pump and waiting for t
data is stored in the EEPROM. After changing the contents of the EEPROM, the
checksum must be recalculated and written (see
In order to enter the command mode, a specific command sequence must be send after a
power-on reset and during the time slot t
command sequence must overdrive the output buffer of the KMA199 (I > I
