Notes: • This register must always be accessed in halfwords.
• For these bits to be enabled, the ADDDAEN bit (A-D Disconnection Detection Assist Function Control Register bit 7) must
be set to "1" before setting these bits.
In order to prevent the A-D conversion result from being affected by the analog input voltage wrapping around
from any preceding channel, the A-D Disconnection Detection Assist Method Select Registers are used to
control the conversion start state by selecting whether to discharge or precharge the chopper amp capacitor
before starting regular conversion operation.
