Flasher ST7 Target system interface
Target system interface for Flasher ST7
The target system interface from FLASHER to target system has to be connected to the 10 pin connector, (pin 1 is marked at the connector) as shown in the diagram.
| Pin nr. | Signal | Function | Specification/remarks. |
|---|---|---|---|
| 1 | GND | Common signal ground | --- |
| 2 | ICCDATA | Data signal for ICC protocol communication | Open collector output with active pull up |
| 3 | GND | Common signal ground | --- |
| 4 | ICCCLK | Clock signal for ICC protocol communication | Open collector output with active pull up |
| 5 | GND | Common signal ground | --- |
| 6 | RESET | Target CPU reset | FLASHER output (Note 1) |
| 7 | VDD | Target supply voltage | Supplies FLASHERs target interface |
| 8 | ICCSEL/VPP | Programming voltage for target CPU | 12V programming voltage, also used to enter ICC mode |
| 9 | OSC_CLK | Target CPU clock | Supplies system clock to target |
| 10 | -- | -- | Not used for ST7, leave open |
Note 1:
If RESET of target system is driven by a reset circuitry with active high driver, RESET output of FLASHER must not be connected directly to CPU reset of target.
