Programmable Function I/O
The USB-1210 supports powerful programmable I/O function pro-
vided by an FPGA chip, configurable as LVTTL DI/DO, 32-bit
timer/counters, and PWM output. These signals are single-ended
and 5 V LVTTL-compliant.
LVTTL DI/DO
Programmable function I/O can be used as static LVTTL-compli-
ant 8-CH digital input and 4-CH digital output. You can read/write
these I/O lines by software polling, with sample and update rate
fully controlled by software timing.
*Not used in DI/O

ter sets featuring:
X
Count up/down controllable by hardware or software
X
Programmable counter clock source (internal clock up to 80
