On second thought, is this really correct ?
I had another look into the datasheet. It seems to me that the chip
may support up to 9 different addresses, though that is a bit vague
since the datasheet first claims that the address would be 0x4c,
only to go on and list the 9 addresses (0x48 to 0x4f as well as 0x37)
in the next paragraph.
Thanks,
Guenter
