:BSIZe?
This command sets the digital I/O bit size to 3 or 4. In the 3-bit mode,
digital I/O line 4 becomes EOT, /EOT, BUSY, or /BUSY based on the
SOUR3:TTL4:MODE and SOUR3:TTL4:BST commands above. In 4-
bit mode, digital I/O line 4 is controlled manually if
SOUR3:TTL4:MODE is set to EOT. If SOUR3:TTL4:MODE is set to
BUSY, operation is identical to the 3-bit mode. The 16-bit size is avail-
able with the 2499-DIGIO option connected to the digital I/O port.
This command is not affected by *RST, :SYSTem:PRESet, or *RCL.
This action command is used to immediately restore the digital output
lines to the output pattern defined by the :TTL:LEVel command.
