I've read it with vvdi, upa and miniprog... all the same reading... I don't know what I'm doing wrong, I'm reading it as 93c56 8 pin...

93sc56 14pin:
pin 2 to pin 1 (93c56 8pin) -----> cs
pin 3 to pin 2 (93c56 8pin) -----> sk
pin 5 to pin 3 (93c56 8pin) -----> di
pin 6 to pin 4 (93c56 8pin) -----> do
pin 9 to pin 5 (93c56 8pin) -----> gnd
pin 13 to pin 8 (93c56 8pin) ---> vcc
