Figure 16: Bus timing for the READ commands

In case of a WRITE command, the device stays in slave communication mode and will not switch to master communication

mode.

When using other commands like DOWNLOAD, UPLOAD, etc. instead of READ or WRITE, it does not matter what is written

in the address fields (ADDR1, ADDR2).

8.2.1

Unblock

The Unblock command can be used to reset only the one-wire interface of the AS5163 in order to recover the possibility to

communicate again without the need of a POR after a stacking event due to noise on the bus line or misalignment with the

AS5163 protocol.

The command is composed by a not idle phase of at least 6 TBIT followed by a packet with all 20 bits at zero (see picture

below).
