7.5-1 Common Commands
*CLS
Clears the ESR, the error queue and the RQS bit. Also terminates all
pending operations. When writing programs, use before each procedure
to avoid buffer overflow.
*ESE
Loads a byte into the Event Status Enable register. The command is
entered with a decimal number that, when converted to binary, enables
the right bits in the Event Status Register. For example:
*ESE 133
When 133 is converted to binary it is 10000101. Bits 7, 2, and 0 will be
enabled.
*ESE?
Returns the contents of the Event Status Enable register. The value
returned is a decimal. For example, if the register has the following
settings:
10000101 than the value returned will be 133.
