The startup time is defined as the time until the Status Register EXC_OK flag goes to ‘1’ (sensor excitation has stabilized).
Reading from the device during this time interval causes the device to respond with Error Code.
The time to stable data is defined as the time from the end of t
Angular rate data can however be read from the device during this time interval.
Internal reset signal is defined for supply voltage above V .
Internal reset is activated when the supply voltage passes V
0.1V).
The RARH and RARLX commands return the Error Code when AV ≤ V
For correct OTP power-down a reset pulse width of minimum 50 µs is needed.
By design.
