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
ISAC-SX TE.
Interrupt Request
INT becomes active low (open drain) if the ISAC-SX
TE requests an interrupt.
The polarity can be reprogrammed to high active
with push-pull characteristic.
Reset
A LOW on this input forces the ISAC-SX TE 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 data clock signal 1.536 MHz
(double bit clock).
Bit Clock
IOM-2 interface bit clock signal 768 kHz
(single bit clock).
Data Downstream
IOM-2 data signal in downstream direction.
