Function
• Non-Multiplexed Bus Mode:
Address Bus
Address bus transfers addresses from the
microcontroller to the IPAC-X. For indirect address
mode only A0 is valid (A1-A7 to be connected to
VDD).
• Multiplexed Bus Mode:
Not used in multiplexed bus mode. In this case A0-
A7 should directly be connected to VDD.
• Multiplexed Bus Mode:
Address/data bus
Transfers addresses from the microcontroller to the
IPAC-X and data between the microcontroller and
the IPAC-X.
• Non-Multiplexed Bus Mode:
Data bus
Transfers data between the microcontroller and the
IPAC-X.
• Multiplexed Bus Mode:
Address/data bus
Address/data line AD5 if the parallel interface is
selected.
• Non-Multiplexed Bus Mode:
Data bus
Data line D5 if the parallel interface is selected.
SCI - Serial Clock
Clock signal of the SCI interface if a serial interface
is selected.
