Comments • Attempting to set bits to other than those values shown will result in an
error -222.
• While this command operates independently of either the
…PARity:TYPE or …SBITs commands, there are two combinations
which are disallowed because of their data frame bit width. The following
table shows the possible combinations:
…BITS …PARity:TYPE …SBITs Frame Bits
7 NONE 1 9 - disallowed
7NONE2 10
7Yes110
7Yes211
8NONE1 10

8 Yes 2 12 - disallowed
• DIAG:BOOT:COLD will set …BITS to 8.
• Related Commands: SYST:COMM:SER[n]:PARity
• *RST Condition: No change
Example Configuring data width to 7 bits.
