Function
• TE-Mode:
Auxiliary Port 0 - 2 (input/output)
These pins are individually
programmable as general input/output.
The state of the pin can be read from
(input) / written to (output) a register.
• LT-T/LT-S/NT Mode:
CH0-2 - IOM-2 Channel Select (input)
These pins select one of eight channels
on the IOM-2 interface.
Mode 0 Select
A LOW selects TE-mode and a HIGH
selects LT-T / LT-S mode (see MODE1/
EAW).
The pin function depends on the setting
of MODE0.
If MODE0=1: Mode 1 Select
A LOW selects LT-T mode and a HIGH
selects LT-S mode.
If MODE0=0: External Awake
If a falling edge on this input is detected,
the SBCX-X generates an interrupt and,
if enabled, a reset pulse.
Reset Output
Low active reset output, either from a
watchdog timeout or programmed by the
host.
Clock Output
A 7.68 MHz clock is output to support
other devices. This clock is not
synchronous to the S interface.
DCA - D-Channel Active Indication
This pin provides an output of the D-
channel bits on the S-bus receive line.
