31.4.7.4 TUNE
Asks the AW for the current baud rate counter value.
31.4.7.5 MEMORY_SPEED_REQUEST
Asks the AW for the relative speed between the aWire clock (RC120M) and the SAB interface.
31.4.7.6 CHIP_ERASE
This instruction allows a programmer to completely erase all nonvolatile memories in the chip.
This will also clear any security bits that are set, so the device can be accessed normally. The
command is acked immediately, but the status of the command can be monitored by checking
the Chip Erase ongoing bit in the status bytes received after the STATUS_REQUEST
command.
31.4.7.7 DISABLE
Disables the AW. The AW will respond with an ACK response and then disable itself.
