ATD0 External Trigger Input Connection
The ATD_10B8C module includes four external trigger inputs ETRIG0, ETRIG1, ETRIG, and ETRIG3.
The external trigger allows the user to synchronize ATD conversion to external trigger events.
Table 1-15
shows the connection of the external trigger inputs on MC9S12XDP512.
See
Section Chapter 5, “Analog-to-Digital Converter (S12ATD10B8CV3)
for information about the
analog-to-digital converter module. When this section refers to freeze mode this is equivalent to active
BDM mode.

ATD1 External Trigger Input Connection
The ATD_10B16C module includes four external trigger inputs ETRIG0, ETRIG1, ETRIG, and ETRIG3.
The external trigger feature allows the user to synchronize ATD conversion to external trigger events.
Table 1-16
shows the connection of the external trigger inputs on MC9S12XDP512.
See
Section Chapter 4,“Analog-to-DigitalConverter(ATD10B16CV4)BlockDescription
forinformation
about the analog-to-digital converter module. When this section refers to freeze mode this is equivalent to
active BDM mode.
