NOTE
The Memory Stick Host Controller is designed to meet the timing
requirements per Sony's Memory Stick Pro Format Specifications
document. Tables in this section details the specifications requirements for
parallel and serial modes, and not the MCIMX31 timing.
Table 51. Serial Interface Timing Parameters1
1 Timing is guaranteed for NVCC from 2.7 through 3.1 V and up to a maximum overdrive NVCC of 3.3 V. See
NVCC restrictions described in Table 8, "Operating Ranges," on page 13.
