HP 3314A Operating Manual

THE STATUS BYTE
The Status Byte is an 8 bit word that the 3314A will output when involved in a
Serial Poll. The
state of each bit (1 or 0) indicates the status of an internal 3314A
function. A bit will be set after that bit has been unmasked and the bit condition
is satisfied. After the Status Byte is sent (all bits reset to 0), the bitlsl will not be
set again if the condition(s) does not change.
Exceptions that automatically reset a bit-and send another SRO message-immediately
after the 3314A sends its Status Byte are:
OVERLOAD
TRIGGER
when in Gate Mode
BUSY FLAG (no SRO sent)
The following statement reads the 3314A's Status Byte.
