BRQ
: This LED flashes as any Bus Request line (BR[3:0]) is active.
SRES
: This LED flashes as the SYSRES is active.
DTK
: This LED turns on if the cycle just executed was terminated with a DTACK asserted
by a slave; it remains on until the next cycle.
BERR
: This LED turns on if the cycle just executed was terminated with a BERR; it
remains on until the next cycle.
The LEDs status can be monitored also via the relevant registers (0x20 through 0x25),
when the module operates as slave; in this case the VME cycle executed for the LED
display readout does not cause the display update: the display shows the status related
to the previous cycle.
