DEVICE-DEPENDENT ERROR REGISTER
The contents of the Device-Dependent Error Register can be read to determine what event has
caused the DDE bit in the Event Status Register to be set. The CDE? and LDE? queries are used as further
discussed below.
The LDE? query request the latched error status. The response is a bit-mapped 16-bit
word indicating the error conditions that have occurred since the last read of the
register. Reading the contents of the register also clears it. See
Table 4-6
for a bit
evaluation of the Device-Dependent Error Register.
The CDE? query request the current device error. The response to this query is also a bit-
mapped 16-bit word as detailed in
Table 4-6
. Reading this register has no effect on it.
