Description of internal registers
STCF03
23/35
8.10
F_RUN
This bit is kept HIGH by the STCF03 during Flash mode. By checking this bit, the μP can
verify if the Flash mode is running or has been terminated by the Time Counter.
8.11
LED_F
This bit is set by the STCF03 when the voltage seen on the LED pin is V
REF2
>5.3 V during
a Torch or Flash operation. This condition can be caused by an open LED, indicating a LED
failure. The device automatically goes into Ready mode to avoid damage. Internal high
frequency filtering avoids false detections. This bit is reset by the STCF03 following a read
operation of the STAT_REG.
8.12
NTC_W
This bit is set HIGH by the STCF03 and the ATN pin is pulled down, when the voltage seen
on the pin Rx exceeds V
REF4
= 0.56 V. This threshold corresponds to a warning temperature
value at the LED measured by the NTC. The device is still operating, but a warning is sent to
the μP. This bit is reset by the STCF03 following a read operation of the STAT_REG.
8.13
NTC_H
This bit is set HIGH by the STCF03 and the ATN pin is pulled down, when the voltage seen
on the pin Rx exceeds V
REF5
. This threshold (1.2V) corresponds to an excess temperature
value at the LED measured by the NTC. The device is put in Ready mode to avoid damaging
the LED. This bit is reset by the STCF03 following a read operation of the STAT_REG.
8.14
OT_F
This bit is set HIGH by the STCF03 and the ATN pin is pulled down, when the chip over-
temperature protection (~140°C) has put the device in Ready mode. This bit is reset by the
STCF03 following a read operation of the STAT_REG.
