11.1 Serial Interface Unit (Type ID: 0101)
The Serial Interface Unit contains 32 bits of data:
Note that the angle information is only valid, if the Hall Sensor Front-end is configured properly. See Table 16 for
more information.
11.1.1 12-bit Angle Information
The 12-bit angle data consists of two blocks: the upper 10-bits in bytes 1 & 2 and the lower two bits in byte 4.

This address is also modified with the analog mode setting
Writing a value to any of the SIN- COS- registers halts the conversion loop and calculates an angle that is given
by the values in the SIN and COS registers. A Read command from these registers restarts the automatic
conversion loop.
Writing a value to the AGC counter register halts the automatic gain control loop and sets the AGC to the value
written in this register. The angle conversion loop continues to operate. A Read command from the AGC register
restarts the automatic gain control loop.
