BIT VALUE | ACTION |
---|---|
0 | Enable all writes as permitted in bit5 or bit6 |
1 | Disable all writes except for the WRITE_PROTECT command. (bit5 and bit6 must be 0 to be valid data) |
In any case, only one of the three bits may be set at any one time. Attempting to set more than one bit results in an alert being generated and the cml bit is STATUS_WORD being set. An invalid setting of the WRITE_PROTECT command results in no write protection.
Data Byte Value | ACTION |
---|---|
1000 0000 | Disables all WRITES except to the WRITE_PROTECT command. |
0100 0000 | Disables all WRITES except to the WRITE_PROTECT, and OPERATION commands. |
0010 0000 | Disables all WRITES except to the WRITE_PROTECT, OPERATION, ON_OFF_CONFIG, and VOUT_COMMAND commands. |
