1. Tolerance limits assume RZQ of 240Ω (±1 percent) and are applicable after proper ZQ cali-
2. Measurement definition for mismatch between pull-up and pull-down (MM
If either the temperature or the voltage changes after I/O calibration, the tolerance limits
listed in Table 42 can be expected to widen according to Table 43 and Table 44 on
page 58.
