Functionally, this pin is an output or an input, but structurally it is an I / O because it either sample configuration input during reset, is a muxed pin, or has other manufacturing test functions. This pin will therefore be described as an I / O for boundary scan. 2. This output is actively driven during reset rather than being tri-stated during reset. 3. MDIC[0] is grounded through an 162Ω precision 1% resistor and MDIC[1] is connected to GVDD through an 162Ω precision 1% resistor. For either full or half driver strength calibration of DDR IOs, use the same MDIC resistor value of 162Ω. Memory controller register setting can be used to determine automatic calibration is done to full or half drive strength. These pins are used for automatic calibration of the DDR3L/DDR4 IOs. The MDIC[0:1] pins must be connected to 162Ω precision 1% resistors. LS1021A Ball Map and Pin List QorIQ LS1021A Data Sheet, Rev. 5, 09/2017 NXP Semiconductors 49 |
