PA<0 ..7 > DGND Inputor
Output
PortA—These pins are port A of the extra digital I/O signals
onthe AT-MIO-16DE-10.
PB<0..7> DGND Inputor
Output
PortB—These pins are port B of the extra digital I/O signals
onthe AT-MIO-16DE-10.
PC<0..7> DGND Inputor
Output
PortC—These pins are port C of the extra digital I/O signals
onthe AT-MIO-16DE-10.
+5V DGND Output +5VDC Source—Thesepinsarefusedforupto1Aof
+5V supply. The fuse is self-resetting.
SCANCLK DGND Output ScanClock—This pin pulses once for each A/D conversion
inthe scanning modes when enabled. The low-to-high edge
indicateswhen the input signal can be removed from the
inputor switched to another signal.
EXTSTROBE* DGND Output ExternalStrobe—Thisoutput can be toggled under software
controlto latch signals or trigger events on external devices.
PFI0/TRIG1 DGND Input
Output
PFI0/Trigger1—As an input, this is either one of the
ProgrammableFunction Inputs (PFIs) or the source for
thehardware analog trigger. PFI signals are explained in
theTiming Connections section later in this chapter.
Thehardware analog trigger is explained in the Analog
Triggersection of Chapter 3, Hardware Overview.
Analogtrigger is available only on the AT-MIO-16E-1,
AT-MIO-16E-2,AT-MIO-16XE-10, AT-AI-16XE-10,and
theAT-MIO-64E-3.
Asan output, this is the TRIG1 signal. In posttrigger data
acquisitionsequences, a low-to-high transition indicates
theinitiation of the acquisition sequence. In pretrigger
applications,a low-to-high transition indicates the initiation
ofthe pretrigger conversions.
PFI1/TRIG2 DGND Input
Output
PFI1/Trigger2—As an input, this is one of the PFIs.
Asan output, this is the TRIG2 signal. In pretrigger
applications,a low-to-high transition indicates the initiation
ofthe posttrigger conversions. TRIG2 is not used in
posttriggerapplications.
PFI2/CONVERT* DGND Input
Output
PFI2/Convert—Asan input, this is one of the PFIs.
Asan output, this is the CONVERT* signal. A high-to-low
edgeon CONVERT* indicates that an A/D conversion is
occurring.
