Camera interface (DCMI) timing specifications

5.3.27

SD/SDIO MMC card host interface (SDIO) characteristics

Unless otherwise specified, the parameters given in Table 81 are derived from tests

performed under ambient temperature, fPCLKx frequency and VDD supply voltage conditions

summarized in Table 10.

Refer to Section 5.3.16: I/O port characteristics for more details on the input/output alternate

function characteristics (D[7:0], CMD, CK).
