13.2.3 MDMA mode
[1]
Tcy1 is the total cycle time, consisting of command active time tw1 and command recovery (inactive) time tw2, that is, Tcy1 = tw1 + tw2.
Minimum timing requirements for Tcy1, tw1 and tw2 must all be met. As Tcy1(min) is greater than the sum of tw1(min) and tw2(min), a host
implementation must lengthen tw1 and/or tw2 to ensure that Tcy1 is equal to or greater than the value reported in the IDENTIFY DEVICE
data. A device implementation shall support any legal host implementation.
Table 110. MDMA mode timing parameters
VCC(I/O) = 1.65 V to 3.6 V; VCC(3V3) = 3.3 V; VGND = 0 V; Tamb = 40 °C to +85 °C; unless otherwise specied.
