OCD Interface
The Z8FMC16100 Series Flash MCU device includes an integrated on-chip debugger
(OCD) that provides advanced debugging features, including:
•
•
•
•
The OCD consists of four primary functional blocks: Transmitter, Receiver, Autobaud
Generator, and Debug Controller.
The OCD uses the DBG pin for communication with an external host. This one-pin
interface is a bidirectional open-drain interface that transmits and receives data. Data
transmission is half-duplex, in that transmit and receive cannot occur simultaneously.
