Note 1: Parameter guaranteed by design. (t_osLH = |t_pLHm − t_pLHn|, t_osHL = |t_pHLm − t_pHLn|)
Note: An is a host side signal. Bn is a card side signal.
V_CCB is supplied from the built-in LDO.

Note 3:
C_PD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load.
Average operating current can be obtained by the equation:
I_{CC (opr)} = C_PDï½¥V_CCï½¥f_IN + I_CC/6 (per bit)
