4 Operation case
4.1 One device SPI mode, unidirectional – 3 wire
The AS5047P adapter board can be directly connected to an industry standard SPI port of a
microcontroller. The minimum connection requirements for unidirectional communication between
the microcontroller and the AS5047P are MISO, CLK, CSn. In this case the MOSI pin is tied to VDD
which will result in reading only the 14-bit Angle Register (0x3FFF). See AS5047P datasheet
register table, register 0x3FFF.

4.2 One device SPI mode, bidirectional – 4 wire
If it’s needed to read other registers than the Angle Register (0x3FFF) or to write to registers of the
AS5047P the MOSI connection is required.
