Signal
Description
CASE_OPEN#
CASE OPEN, used to detect if the system case has been opened. This signal’s status is readable,
so it may be used like a GPI when the Intruder switch is not required.
SMBC
SMBus Clock signal
SMBD
SMBus Data signal
S3#
S3 sleep mode, active low output, optionally used to deactivate external system.
S5#
S5 sleep mode, active low output, optionally used to deactivate external system.
PWR_OK
Power OK, signal is high if no power failures are detected. (This is not the same as the P_OK
signal generated by ATX PSU).
EXT_BAT
(External Battery) option for conn terminal of an external primary cell battery (2.5 V -
3.47 V) (– terminal connected to GND). The external battery is protected against charging and
can be used with/without the on-board battery installed.
SB3V3
Max. load is 0.75 A (1.5 A < 1 sec.)
SB5 V
S5 V supply.
TOUCH_I2C_DAT
Serial I/O – I2 C interface data Line
TOUCH_I2C_CLK
Serial I/O – I2 C interface clock Line
TOUCH_RST#
Serial I/O –interface reset
TOUCH_INTR#
Serial I/O –interrupt line
GPIO0..17
General Purpose Inputs / Output. These Signals may be controlled or monitored through the use
of the KT-API-V2 (Application Programming Interface).
