Data Sheet – SPI Communication
10.5 SPI Interface Commands
10.5.1 READ Command
For a single READ command two transmission sequences are necessary. The first package written to the AS5055
contains the READ command (MSB high) and the address the chip has to access, the second package transmitted to
the AS5055 device can be any command the chip has to process next. The content of the desired register is available
in the MISO register of the master device at the end of the second transmission cycle.
Figure 5. READ Command
10.5.2 WRITE Command
A single WRITE command takes two transmission cycles. With a NOP command after the WRITE command you can
verify the sent data with three transmission cycles because the data will be send back during the NOP command.
