In case of READ or READ128 command (see Figure 15) the idle phase between the command and the answer is 10 TBIT (TSW).

Master Communication Mode
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).
8.1.3
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 Figure 17) .
