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 MC9S12XDP512RMV2.

See Section Chapter 5, “Analog-to-Digital Converter (S12ATD10B8CV2) 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 MC9S12XDP512RMV2.

See Section Chapter 4, “Analog-to-Digital Converter (ATD10B16CV4) Block Description for information

about the analog-to-digital converter module. When this section refers to freeze mode this is equivalent to

active BDM mode.
