Claim 0:
1. An apparatus, comprising:
a communication buffer configured to receive a clock signal from an external controller;
a logic circuit coupled to the communication buffer and configured to:
count a first number of input transitions of the clock signal for a set time period;
store in one or more sets of latches a count value of the first number of input transitions;
adjust an input bias level for the communication buffer after counting the first number of input transitions;
count a second number of input transitions of the clock signal for the set time period using the adjusted input bias level;
generate a comparison result based on the second number of input transitions and the first number of input transitions; and

a data communication circuit coupled to the logic circuit and configured to:
send the comparison result to the external controller.
