AS5047P − Detailed Description

The parity bit PARD must be calculated from the 16-bit data.

In an SPI write transaction, the write command frame (e.g. Write

ADD[n]) is followed by a data frame (e.g. DATA [x]). In addition

to writing an address in the AS5047P, a write command frame

causes the old contents of the addressed register (e.g. DATA [y])

to be sent on MISO in the following frame. This is followed by

the new contents of the addressed register (DATA [x]) as shown

in Figure 18.
