when battery voltage is first applied to V
PWON flag is set, UV
disabled. The primary function of the PWON flag is to pre-
vent the MAX13041 from entering sleep mode (and there-
by disabling external voltage regulators) before the
protocol controller establishes control through EN and
STB. The PWON flag is externally indicated as a logic-low
on ERR when the MAX13041 is placed into PWON/listen-
only mode from standby mode, go-to-sleep command
mode, or sleep mode. The PWON flag is cleared when
the MAX13041 enters normal mode.
The wake-up flag is set when a local or remote wake-up
request is detected. A local wake-up request is gener-
ated when the logic level on WAKE changes and
remains stable for t
request is generated upon the detection of two domi-
nant bus cycles, each followed by a recessive bus

The wake-up source flag is set concurrently with the
wake-up source flag when a local wake-up event is
detected. The wake-up source flag can only be set
after the PWON flag has been cleared. The flag is
cleared when the MAX13041 leaves normal mode and
during initial power-on. The wake-up source flag is
