PIN DESCRIPTIONS, (CON’T)
C12, C13 and GIO0
The SPICoderTM 06 offers pins C12,
C13 and GIO0. C12 and C13 are
used as additional column pins in
order to accommodate larger-size
keyboards, such as the Fujitsu
FKB1406 palmtop keyboard. GIO0
is a programmable input/output
switch; it can also be used as a
wake-up signal. The programming
of the GIO0 is explained on page 8
of this document.
XSW
The XSW pin is dedicated to an
external switch. This pin is handled
differently than the rest of the switch
matrix and is intended to be
connected to a switch physically
located on the outside of the unit.
SW0
The SW0 pin is a dedicated input
pin for a switch.
PWR_OK
The PWR_OK is an active low pin
that monitors the battery status of
the unit. When the UR5HCSPI-06
detects a transition from high to low
on this pin, it will immediately enter
the STOP mode, turn the LED off
and remain in this state until the
batteries of the unit are replaced
and the signal is deasserted.
