Function
• Non-Multiplexed Bus Mode:
Address Bus
Address bus transfers addresses from the
microcontroller to the ISAC-SX. 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
ISAC-SX and data between the microcontroller and
the ISAC-SX.
• Non-Multiplexed Bus Mode:
Data bus
Transfers data between the microcontroller and the
ISAC-SX.
• 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.
