If any of the interrupt sources listed under the “Wake-from-Sleep” column is asserted, then the system will transition out of the

low sample rate Auto-Sleep mode to the user-specified fast sample rate provided the user-specified wake event function is

enabled in register CTRL_REG3.

If the Auto-Sleep interrupt is enabled, a transition from Active mode to Sleep mode and vice-versa will generate an interrupt.

If CTRL_REG3[fifo_gate] = 1, transitioning to Auto-Sleep mode will preserve the FIFO contents, set SYSMOD[fgerr] (FIFO Gate

error), and stop new acquisitions. The system will wait for the FIFO buffer to be emptied by the host application before new

samples can be acquired.
