Return Format
The command reads the condition register and returns a decimal value which corresponds to the binary-weighted sum of all bits set in the register (see table above). For example, if bit 1 (decimal value = 2) and bit 4 (decimal value = 16) are set, this command will return "+18".
Example
The following command reads the condition register (bit 4 is set).
