FLASHER 5 Manual 9

Target interface for ST9 Controller

The clocked synchronous interface from Flasher to target system is built with a 10 pin dual in line pin con-

nector,(pin1 is marked at the connector) at the front of FLASHER. Function depends on selected target.

Pin no. Signal Function for ST9F120 Specification / remarks

1 VCCS Positive supply voltage of target Input 3.0 .. 5.5V to supply the interface

2 Not used for ST9, leave open

3 RxCLK Target CPU Serial clock input FLASHER Output

4 SIN0 Target CPU Serial data input FLASHER Output

5 TxCLK Target CPU Serial clock output FLASHER Input with 47k Pull-Up

6 SOUT0 Target CPU Serial data output FLASHER Input with 1.2k Pull-Down

7 GND Common signal ground ---

8 RESET RESET signal of target system FLASHER Output

9 Not used for ST9, leave open

10 Not used for ST9, leave open

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.

When using Pull-Ups in Your target system, the Pull-Up at SOUT0 must not be smaller than 47kOhm.

Target system interface for ST92F120 or ST92F150

Caution:

Before connecting the target with Flasher, ensure that there is NO difference in the ground potential

between Flasher and target.

When the Flasher is connected to a PC via RS232C cable, ensure that the PC and the target operate on

the same ground potential.

Connect the ground lines from PC and your target before connecting the Flasher to the target.

If a ground potential difference between Flasher and target exists, the Flasher may be damaged.
