Flasher 5: Target system interface for FLASHER 5 |
|
|
|
|
The clocked synchronous interface from FLASHER to target system has to be connected
to the 10 pin dual in line pin connector, (pin 1 is on the top left, marked at the connector)
as shown in the diagram. | Pin nr. | Signal | Function | Specification/remarks. | | 1 | VCCS | Positive supply voltage of target | Input 3.0 .. 5.5V to supply the interface | | 2 | BUSY | Target CPU Busy signal output. | FLASHER Input with Pull-Up to internal 3.3V | | 3 | SCLK | Target CPU Serial clock (input) | FLASHER Output, CMOS driver via 220 Ohms | | 4 | RxD | Target CPU Serial data input | FLASHER Output, CMOS driver via 220 Ohms | | 5 | CE | Chip enable signal of target CPU | FLASHER Input/Output | | 6 | EPM | EPM signal of target CPU | FLASHER Input/Output | | 7 | GND | Common signal ground | --- | | 8 | RESET | RESET signal of target system | FLASHER Output, CMOS driver via 220 Ohms | | 9 | CNVss | Target CPU CNVss signal | FLASHER analog Output | | 10 | TxD | Target CPU Serial data output | FLASHER Input/Output | The pull-up resistors of outputs are connected to VCCS.
If RESET of the 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. For M16C/62 or M16C/80 targets you do not have to connect RESET to FLASHER; you can always manually reset your target system after connecting FLASHER.
