4. INTERFACE TYPES
This section describes two interfaces, In-Circuit Programming (ICP) and On-Board
Programming (OBP) of HC912-Programmer.
4.1 IN-CIRCUIT PROGRAMMING
In-Circuit programming interface is basic for HC912-Programmer. With this interface HC912-
Programmer automatically detects target MCU bus speed. Ceramic resonator connected to target
MCU must be in range from 2 MHz to 16 MHz. If target MCU secured (9S12 devices) or BDM
module disabled (912 devices) there is no way to establish connection between MCU and HC912-
Programmer.
& Note: ECLK Pin on target MCU must be co nnected to circuit via resistor

gure 1).
1Kohm or higher to avoid damaging of this pin.

4.2 ON-BOARD PROGRAMMING
On-board programming interface designed for establishing connection with target device when
MCU secured (9S12 devices) or BDM module disabled (912 devices). This interface allows
