we make a mistake in sp370 program, and we lock the IC.
Now we want to unlock the IC, we try to enter test mode(when the sp370 lock,we can not enter program mode) to erase the program and make the sp370 unlock.
But we communicate the SP370 by I2C and it do not communicate success.
Please tell us how we can unlock the SP370 to advoid our losses.
Thanks!
