Register Value
Mode 0x00008020
Snapshot Configuration 0x00000009
Preload0 0x00000000
Pulse Generator
Generate an output pulse on ExtOut in response to a trigger signal applied to the IX input. Also, a software trigger can
be invoked by calling S826_CounterPreload. ExtOut must be routed to a DIO channel (see
S826_DioOutputSourceWrite).
Register Value
Mode 0x004C0520 (retriggerable), or
0x00CC0520 (non-retriggerable)
Preload0 Pulse duration in µs
PWM Generator
Output a pulse width modulation (PWM) signal on ExtOut, which must be routed to a DIO channel through the
DIO_out signal routing matrix (see S826_DioOutputSourceWrite).
Register Value
Mode 0x01682020
Preload0 PWM “on” time in µs
Preload1 PWM “off” time in µs
Synchronized PWM generators can be implemented by configuring the PWM channels as hardware triggered one-shots
(pulse generators). Use an additional channel to generate a common trigger for the PWM channels; this channel should
be configured to generate periodic output pulses at the desired PWM frequency. The duty cycle of each PWM channel
is controlled by adjusting its output pulse width.
