Other Parts Discussed in Thread: TLV320AIC3254
We are testing a TLV320AIC3254 QFN32 package using the L138 Processor Boundary Scan pins that it is connected to for test stimulus and response. Does the LDO_IN voltage need to be present for the I2C port to work? Does the Master Clock have to be running? If the Master Clock must be running what is it's relationship to the SCL clock timing please?
