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.

Target interface to M16C62/M16C80/M32C (M30624/M30625/M30800)
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.
