The U5R supply pin provides a typically 5V supply voltage to the external E
2
PROM, and has a
biasing capability only for this purpose.
Programming of the E
2
PROM is possible with the E
2
PROM soldered-in into the AS-Interface
Slave unit's pc-board by accessing the SCL / SDA serial bus with an external programming
hardware.
