Stop mode powers down the sigma-delta converter and halts clock to the modulus counter. Exit
from Stop enables the sigma-delta converter and the clock to the modulus counter but due to the
converter recovery time, the integration result should be ignored.
Wait mode with SSDWAI bit set powers down the sigma-delta converter and halts the clock to the
modulus counter. Exit from Wait enables the sigma-delta converter and clock to the modulus
counter but due to the converter recovery time, the integration result should be ignored.
Clearing SDCPU bit powers down the sigma-delta converter.
