goes low when an unmasked interrupt event is
detected on any of the internal interrupt sources. Note
that INTB will remain low until all active, unmasked
interrupt sources are acknowledged at their source.
during TEMAP-84 register accesses.
The CSB input has an integral pull up resistor.
during TEMAP-84 register read accesses. The
TEMAP-84 drives the D[7:0] bus with the contents of
the addressed register while RDB and CSB are low.
during a TEMAP-84 register write access. The D[7:0]
bus contents are clocked into the addressed register
on the rising WRB edge while CSB is low.
Bidirectional Data Bus (D[7:0]). This bus provides
TEMAP-84 register read and write accesses.
