IN CIRCUIT EEPROM CONFIGURATION
The EEPROM remains on the PCB and is reprogrammed via
the IIC bus.
No Name Function
1 VDD Positive supply
2 CNF A positive edge on CNF with DIRO high will
trigger a configuration reload
3 SDA Serial data pin
4 SCK Serial clock pin
5 FOUT LED pin of device
6 DIRO DIRO need to be high before CNF is pulsed
to trigger a reload
7 VSS Negative supply voltage

ISOLATED PC INTERFACE MODULE
OPERATION
The isolator module connects to a standard PC printer port by
means of an extender cable on the one side and to the
PM9607AP on the other side. The PC is completely isolated
form the evaluation module and can be used to program the
EEPROM on the PM9607AP module safely.
The SA9607P is designed to be the bus master and does not
support multi master mode. Resistor R22 is used to overdrive
the clock signal of the SA9607P during programming.
