8.1.9 PASS2FUNC

Figure 23 shows the format of the frame.

Figure 23. Frame Organization of the PASS2FUNCTION Command

The command consists of one frame received by the AS5163 (slave communication mode). This command stops the communication receiving

mode, releases the reset of the DSP of the AS5163 device and starts to work in functional mode with the values of the SFR currently written.

The access is performed with CMD field set to 0x7.

8.1.10 READ

Figure 24 shows the format of the frame.

Figure 24. Frame Organization of the READ Command

The command is composed by a first frame sent to the AS5163. The device is in slave communication mode. The device remains for the time

AS5163.

The access is performed with CMD field set to 0xB.

When the AS5163 receives the first frame, it sends a frame with data value of the address specified in the field of the first frame.

Table 17 shows the possible readable data information for the AS5163 device.

An even parity bit is used to guarantee a correct data transmission. The parity bit (P) is generated by the 16 data bits. The MSB of the CMD

dummy (P) is reserved for the parity information.
