KMA200
Programmable angle sensor
13.2 Command mode
This mode is used for calibration and programming. The KMA200 is controlled with serial
interface commands.
To activate the command mode, the following initialization procedure must be executed
during power-on reset. The pin CS
must be constantly held on HIGH level and
pin CLK/OUT2 must be constantly held on LOW level during power-on. This condition has
to start during reset and must be valid during the following initialization phase of the
KMA200 for at least 1 ms. CS
and CLK are internally weak pull-up so that at least CLK
must be actively driven. If these conditions are valid, the KMA200 starts in command
mode. At all other combinations or if the levels are not constant for the minimum time of
1 ms, the KMA200 starts in normal operation mode.
The normal operation mode is configured with sixteen 16-bit constants stored in the
on-chip EEPROM.
13.3 Notes to the programming
The KMA200 sensor is delivered in a pre-calibrated and preprogrammed default
condition.
The EEPROM addresses 0, 1, 5, C, D and E are device dependent and pre-calibrated
for each device. A changing of this contents to another value is not allowed,
because the specified data, influenced by these addresses, are no longer valid.
The EEPROM addresses A and B are used to store production related information.
A changing of these values should not be done.
Definition:
Address A: storage the date code. Date code assembly center: day of the year
(maximum 365) + year (maximum 99)

13.4 Write RAM (0nh), read RAM (1nh)
To write data to the RAM the command byte 0nh (n is the address of the data) followed by
the 16-bit data has to be send. To read data from the RAM, the command byte 1nh has to
be send. If CS
is activated again, the RAM contents at the specified address is clocked
out. Note that at power-on addresses 00h to 0Fh are read from the EEPROM into the
RAM.
13.5 Calculate CRC-16 and program EEPROM (30h)
To program the EEPROM, the configuration data has to be written to the RAM addresses
00h to 0Eh. Afterwards, the command byte 30h has to be sent and the EEPROM
programming voltage has to be applied at the V
DD
pin. The KMA200 calculates the
CRC-16 check sum and writes the RAM constants at addresses 00h to 0Fh to the
EEPROM. This command is only executed when the EP bit in the control information word
is logic 0 on power-on. If the EP bit is logic 1, this command is ignored.
