Function
Address Latch Enable
A HIGH on this line indicates an address on the
external address/data bus (multiplexed bus type
only).
ALE also selects the microcontroller interface bus
type (multiplexed or non multiplexed).
Chip Select
A low level indicates a microcontroller access to the
IPAC-X.
Interrupt Request
INT becomes active low (open drain) if the IPAC-X
requests an interrupt.
The polarity can be reprogrammed to high active
with push-pull chracteristic.
Reset
A LOW on this input forces the IPAC-X into a reset
state.
Address Mode
Selects between direct (0) and indirect (1) register
access mode.
Frame Sync
8-kHz frame synchronization signal.
Data Clock
IOM-2 interface clock signal (double clock) (e.g
1.536 MHz in TE mode).
