Note that the legal impedance values (from highest impedance to lowest impedance) for DDR2 (1.8 V) are:

A value of 1111 provides the target for half-strength mode when driver calibration is not used.

Note that the legal impedance values (from highest impedance to lowest impedance) for DDR3 (1.5 V) are:

A value of 0000 should be used for default half-strength mode when driver calibration is not used.

Note that the drivers may either be calibrated to full-strength or half-strength.

5. Clear DDRCDR_1[DSO_MDIC_PZ_OE]

6. After DDRCDR_1[DSO_MDICPZ} is calibrated, set a value of 0000 for

7. Set DDRCDR_1[DSO_MDIC_NZ_OE] to enable the output enable for MDIC[1]

8. After at least 4 cycles, read DDRDSR_1[1]. If the value is 1, then use the next lowest impedance,

9. Clear DDRCDR_1[DSO_MDIC_NZ_OE]

DDRCDR_1[DSO_MDICNZ]

and read DDRDSR_1[1] again. Once a value of 0 is detected, then leave

DDRCDR_1[DSO_MDICNZ] at the calibrated value

1010 (default full-strength impedance)

0111 (default full-strength impedance)
