Digital Input States at Startup

The state of each digital input at startup is stored sequentially starting at bit 0, the least significant bit.

This command can be used to determine which digital input caused the unit to be powered up. The device driver for /gryphon/dev/gpwr reads and clears the latched state of the digital inputs during its initialization and stores the values internally. If other digital inputs are set before the latched inputs are read, more than one bit in the data byte will be set.
