AS5047D − Detailed Description

Figure 15:

SPI Read

Figure 16:

SPI Write Data Frame

Figure 16 shows the structure of the Write Data Frame.

The parity bit PARD must be calculated from the lower 15 bit of

write data frame.

In a SPI write transaction, the write command frame is followed

by a write data frame at MOSI. The write data frame consists of

the new register content, which was addressed is in the

previous command frame.

During data transmission on MOSI, the current register content

is send on MISO. At the next command on MOSI the updated

content of the register is transmitted on MISO, as shown in

Figure 17.
