Registers 0~9 are Swing0_Pre0, Swing1_Pre0, Swing2_Pre0, Swing3_Pre0, Swing0_Pre1, Swing1_Pre1, Swing2_Pre1, Swing0_Pre2, Swing1_Pre2, Swing0_Pre3, they are for [Boost control] and [Swing control] setting. Registers 0~9, bit 3:0 is [Boost control], these bits control post cursor manual, increase the [Boost control] to increase Pre-emphasis value. Registers 0~9, bit 6:4 is [Swing control], these bits control swing manual, increase [Swing control] setting to add Vp-p value for each Swing, Pre. Registers 10~19 are Swing0_Pre0, Swing1_Pre0, Swing2_Pre0, Swing3_Pre0, Swing0_Pre1, Swing1_Pre1, Swing2_Pre1, Swing0_Pre2, Swing1_Pre2, Swing0_Pre3, they are for [R select control] and [R Termination control] setting. Registers 10~19, bit 4:0 is [R select control], these bits are compensation manual, increase it can enhance IO driven strength and Vp-p.
