a. This measurement is made in manual current control mode; i.e. with all output device legs sinking current.
b. This measurement is made in automatic current control mode after at least 64 current control calibration operations to a device and after CCA and
CCB are initialized to a value of 64. This value applies to all DQA and DQB pins.
c. This measurement is made in automatic current control mode in a 25Ω test system with V_TERM= 1.714V and V_REF= 1.357V and with the ASYMA
and ASYMB register fields set to 0.
