Digital Output Configuration
Two output signals are available which may be configured for ON/OFF, PWM or SERVO outputs through the Output
Configuration registers (0x0124 and 0x0126). The remaining outputs are assigned as phantom devices which are
non-configurable. The highlighted entries show typical default configurations.

Rate
The Rate determines the repetition rate, or frequency, of the Digital Output. For On/Off outputs the rate
field is ignored.
PWM Rate
The SP-003/SP-004 supports the following PWM frequencies:
