The command consists of one frame received by the AS5263 (slave communication mode). The OTP cell fuse content will be downloaded into
the SFRs.
The access is performed with CMD field set to 0x5.

The command consists of one frame received by the AS5263 (slave communication mode) and transfers the data from the SFRs into the OTP
fuse cells. The OTP fuses are not permanent programmed using this command.
The access is performed with CMD field set to 0x6.

The command consists of one frame received by the AS5263 (slave communication mode) and it is giving the trigger to permanent program the
non volatile fuse elements.
The access is performed with CMD field set to 0x4.
Note: After this command, the device automatically starts to program the built-in programming procedure. It is not allowed to send other com-
mands during this programming time. This time is specified to 4ms after the last CMD bit.
