Programmable angle sensor
A more detailed description of all customer accessible registers is given in
Section 13.5
.
Both default value and the complete command including the address and write or read
request are also listed.
13.3.1
Write access
To write data to the non-volatile memory, the internal charge pump must be enabled by
setting bits CP_CLOCK_EN and WRITE_EN and waiting for t
cp
. The following procedure
must be performed:
1. Start condition: The master drives a rising edge after a LOW level
2. Command: The master sends a write command (CMD0 = 0)
3. Data: The master sends two data bytes
4. Stop condition: The master drives a rising edge after a LOW level
Figure 15
shows the write access of the digital interface. The signal OWI represents the
data on the bus from the master or slave. The signals: master output enable and slave
output enable indicate when the master or the slave output is enabled or disabled,
respectively.
Note
: As already mentioned in
Section 13.1
, the command mode has to be entered using
the write procedure. If command mode is not entered, communication is not possible and
the sensor operates in normal operation mode. After changing an address, the time t
prog
must elapse before changing another address. Finally the checksum must be recalculated
and written, because the contents of the non-volatile memory have been changed
(see
Section 13.4
).
(1) Missing rising edges generate a time-out condition and the written data is ignored.
(2) If the master does not drive the bus, the bus is defined by the bus-pull.
