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).

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).

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.
