INTB
Output A16
OD
Active low Open-Drain Interrupt (INTB). This signal
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.
CSB
RDB
Input D16
Input B16
Active Low Chip Select (CSB). This signal is low
during TEMAP register accesses. CSB has an integral
pull up resistor.
Active Low Read Enable (RDB). This signal is low
during TEMAP register read accesses. The TEMAP
drives the D[7:0] bus with the contents of the
addressed register while RDB and CSB are low.
WRB
Input C15
Active Low Write Strobe (WRB). This signal is low
during a TEMAP register write access. The D[7:0] bus
contents are clocked into the addressed register on the
rising WRB edge while CSB is low.
