1.
The Nu-Link-Gang power on. STARTx, BUSYx, PASSx, and FAILx are set to logic 1.
2.
To start programming, STARTx needs to be set to logic 0 for TSTART,
.
3.
Programming start-up. BUSYx is set to logic 0 , and might toggle during programming.
4.
When finish programming, BUSYx is set to logic 1, and PASSx or FAILx is set to logic 0.
When BUSYx
is set to logic 1, and PASSx is set to logic 0, means “PASS”.
When BUSYx is set to logic 1, and FAILx
