AS5050A − Registers
The on-chip registers are shown in Figure 22.
Figure 22:
Registers
POR OFF (0x3F22)
Writing the value 0x5A to the POR OFF Register (0x3F22)
deactivates the POR cell and reduces the current consumption
in low power mode (IOFF).
Software Reset (0x3C00)
Writing to the Software Reset Register initiates a Software
Reset. With the RES SPI bit of the Data Package set to 1 it is
possible to reset the SPI registers. After a software reset a new
angle conversion is started; this is needed to set the AS5050A
into an initial state. This angle is not readable by the
microcontroller.
The AS5050A is ready as soon as INT/ is driven low or a minimum
time (treadout) has elapsed.
