Chip Select
, active low. A low on this line selects the PT7D6555 for
read/write operations.
Address Latch Enable
ALE controls the on chip address latch in multiplexed bus mode. While ALE is
high , the latch is transparent. The falling edge latches the current address.
During the first read/write access following reset ALE is evaluated to select the
bus mode.
Interrupt Request
, active low.
This signal is activated when the PT7D6555 requests an interrupt. Due to the
open drain (OD) characteristic of INT multiple interrupt sources can be
connected together.

Frame Synchronization
Input or output in IOM configuration. Direction indication signal in SLD mode.
Data Upstream Input

Depending on the bit OMDR: COS these lines have push pull or open drain
characteristic.
For unassigned channels or when bit OMDR: CSB is reset the pins are in the
state high impedance.
