Function
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 IPAC-
X generates an interrupt and, if enabled, a reset
pulse.
Activation LED
This pin can either function as a programmable
output or it can automatically indicate the activated
state of the S interface by a logic ’0’.
An LED with pre-resistance may directly be
connected to ACL.
Clock Output
A 7.68 MHz clock is output to support other devices.
This clock is not synchronous to the S interface.
Reset Output
Low active reset output, either from a watchdog
timeout or programmed by the host.
