MEMORY_SPEED_REQUEST
STATUS_REQUEST
TUNE
CHIP_ERASE
Asks the AW for a status message.
Table 39-34. STATUS_REQUEST Details
Asks the AW for the current baud rate counter value.
Table 39-35. TUNE Details
Asks the AW for the relative speed between the aWire clock (RC120M) and the SAB interface.
Table 39-36. MEMORY_SPEED_REQUEST Details
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.
