PRODUCTION DATA
This is the normal operating mode of the device. Transitions to other modes:
→ ERROR
The device is forced to go to ERROR in case of:
During the transition to ERROR mode the EC is incremented.
→ LOCKED
In case a dedicated SPI command (SPI_LOCK_CMD) is issued.
→ TESTSTART
The device moves to TESTSTART after detecting that VT < VTTH-L.
→ LPM0
The device can be forced to enter LPM0 with a SPI LPM0 command. During this transition the EC is decremented.
If the EC reaches the NRES value, the device transitions to LPM0 mode and EC is cleared. Depending on the state of the WAKE pin, the device remains in LMP0 (WAKE pin low) or restart to TESTSTART (WAKE pin high). To indicate the device entered LPM0 after EC reached NRES value, a status bit EC_OF (error counter overflow, SYS_STAT bit 3) is set. The EC_OF bit is cleared on read access to the SYS_STAT register.
A watchdog reset in ACTIVE mode only increases the EC, but it does not change the device mode.
