SDMMC characteristics
Unless otherwise specified, the parameters given in Table 98 for SDIO are derived from
tests performed under the ambient temperature, f_PCLKx frequency and V_DD supply voltage
conditions summarized in Table 22: General operating conditions, with the following
configuration:
• Output speed is set to OSPEEDRy[1:0] = 11
• Capacitive load C = 30 pF
• Measurement points are done at CMOS levels: 0.5 ₓ V_DD
Refer to Section 6.3.14: I/O port characteristics for more details on the input/output
characteristics.
