Stop Mode
Entering stop mode causes all clocks to halt and thus the system is placed in a minimum power
standby mode. This aborts any conversion sequence in progress. During recovery from stop mode,
there must be a minimum delay for the stop recovery time, t
conversion sequence.
Wait Mode
Entering wait mode the ATD conversion either continues or aborts for low power depending on the
logical value of the AWAIT bit.
Freeze Mode
In freeze mode the ATD10B8C will behave according to the logical values of the FRZ1 and FRZ0
bits. This is useful for debugging and emulation.
