The address PWMCTRL consists of control bits for configuring the PWM/SDA pin:
Bit 0
Bit 1
Bit 2
Bit 3
Bits[8:4]
Bits[15:9]
The address ConfigRegister1 consists of control bits for configuring the analog and digital parts:
Bits[2:0]
Bit 3
Bits[5:4]
Bit 6
Bit 7
Bits[10:8]
Bits[13:11]
Bit 14
Bit 15
Note: The following bits/registers should not be altered (except with special tools – contact Melexis for such
tools availability) in order to keep the factory calibration relevant:
Ke [15..0] ; Config Register1 [13..11;7;3] ; addresses 00Fh and 019h.

Number of repetitions divided by 2 of sensor 1 and 2 in Extended PWM
mode. The number of repetitions can vary from 0 to 64 times.
2MHz divided by the number written in this place. (128 in case the number is
0.) A single PWM period consists of 2048 clocks and extended PWM of 4096
clocks for each period (2T in figure 6). The 2 MHz clock is valid for the
nominal HFO frequency.
