S4.4 CarProg Motorola HC912 and 9S12 Programmer

manual

For Motorola MPU HC12 series programming use A10 cable.

You can recognize Motorola (Freescale) MPU by maskset:

This MPU maskset is 4C11W.

• First digit Ð4Ñ is mask series number, in practice can be 0, 1, 2, 3, 4 or 5, but for

programming is not important.

• Second 4 symbols is always letter + digit + digit + letter: this is processor maskset or

encrypted processor type. All processor marking can by custom made, like ÐFORD

S2234234Ñ or SC2323454 but always you can find maskset on Motorola or Freescale

processors.

Before programming always select right processor type according maskset.

How to connect CarProg programmer:

For HC12 or 9S12 programming use A10 cable 6 color wires:

BLUE Î Reset signal to MPU;

BROWN Î GND (ground);

GREY Î BKGD communication signal;

RED Î switched +5V;

VIOLET - switched +12V;

Troubleshooting:

CarProg ERROR messages:

• Communication error - no communication between CarProg and Motorola processor -

check MPU type, try to select quartz frequency manually.

To understand better onboard MPU programming problems, you can use table with right

programming signals and voltages, described in table.

If you canÓt read or write MPU with CarProg, check:

did you was select right MPU type;

did quartz resonator Q is the same in circuit board and in CarProg options;

did all programming signals have right form and voltage;
