TOV with Internal MSYNC Mode
When the IMU is providing its own data output requests based on its
internal source’s preconfigured rate, the unit outputs the differential
TOV signal with a 10% duty cycle at the same frequency as the data
output. See the timing diagram shown in Figure 17 on page 18, as well
as the timing parameters in Figure 18 on page 19.
TOV with External MSYNC Active
When the external Master Synchronization Input is configured, the
IMU will simply buffer (i.e., repeat) the MSYNC signal back out to the
TOV signal. Therefore, the timing should closely mirror that of the
external MSYNC signal.
Hardware Restart
Applying a positive RS-422-compliant voltage from pin 5 (EXT-RST (-))
to pin 14 (EXT-RST (+)) will result in a reset. These pins may be left
disconnected until you need to restart the IMU.
