ENABle register
The ENABle register determines whether the associated EVENt bit influences the
summary bit (see below). Each bit of the EVENt register is ANDed (symbol '&')
with the associated ENABle bit. The events of all logical operations of this register
are ORed (symbol '+') and passed on to the summary bit.
ENABle bit = 0: the associated EVENt bit does not affect the summary bit. bit = 1:
if the associated EVENT bit is "1", the summary bit is also set to "1".
This register can be written to and read as required. Reading the register does not
change its contents.
Summary bit
As stated above, the summary bit for each register is derived from the EVENt and
ENABle registers. The result is entered into a bit of the CONDition register of the
next higher register. The device automatically generates the summary bit for each
register. An event may thus cause a service request through all hierarchical
levels.
Note:
The Service Request Enable register (SRE) defined by IEEE488.2 can be
viewed as the ENABle register of the STB. Accordingly, the ESE can be
viewed as the ENABle register of the ESR.
