Input
C7
The active low write strobe (WRB) signal is low
during a TUPP+622 register write accesses
while in Intel bus mode. The D[7:0] bus contents
are clocked into the addressed register on the
rising WRB edge while CSB is low.
RWB
The read/write select (RWB) signal selects
between TUPP+622 register read and write
accesses while in Motorola bus mode. The
TUPP+622 drives the D[7:0] bus with the
contents of the addressed register while CSB is
low and RWB and E are high. The D[7:0] bus
contents are clocked into the addressed register
on the falling E edge while CSB and RWB are
low.
