7 | DEV_RESET | R/W | 0 |
Device reset. Setting this bit performs the equivalent operation of power cycling the device. Any playback operations are immediately interrupted, and all registers are reset to the default values. The DEV_RESET bit self-clears after the reset operation is complete. |

0: Internal trigger Waveforms are fired by setting the GO bit in register 0x0C. 1: External trigger (edge mode) A rising edge on the IN/TRIG pin sets the GO Bit. A second rising edge on the IN/TRIG pin cancels the waveform if the second rising edge occurs before the GO bit has cleared. 2: External trigger (level mode) The GO bit follows the state of the external trigger. A rising edge on the IN/TRIG pin sets the GO bit, and a falling edge sends a cancel. If the GO bit is already in the appropriate state, no change occurs. 3: PWM input and analog input A PWM or analog signal is accepted at the IN/TRIG pin and used as the driving source. The device actively drives the actuator while in this mode. The PWM or analog input selection occurs by using the N_PWM_ANALOG bit. 4: Reserved. 5: Real-time playback (RTP mode) The device actively drives the actuator with the contents of the RTP_INPUT[7:0] bit in register 0x02. 6: Diagnostics Set the device in this mode to perform a diagnostic test on the actuator. The user must set the GO bit to start the test. The test is complete when the GO bit self-clears. Results are stored in the DIAG_RESULT bit in register 0x00. 7: Auto calibration Set the device in this mode to auto calibrate the device for the actuator. Before starting the calibration, the user must set the all required input parameters. The user must set the GO bit to start the calibration. Calibration is complete when the GO bit self-clears. For more information see the Auto Calibration Procedure section. |
