Enhanced Secured Digital Host Controller (eSDHCv2) Timing
Figure 54 shows eSDHCv2 timing, and Table 61 describes the timing parameters (SD1–SD8) used in the
figure. The following definitions apply to values and signals described in Table 61:
LS: low-speed mode. Low-speed card can tolerate clocks up to 400 kHz
FS: full-speed mode. Full-speed MMC card’s clock can reach 20 MHz; full speed SD/SDIO card
clock can reach 25 MHz
HS: high-speed mode. High-speed MMC card’s clock can reach 52 MHz; SD/SDIO card clock can
reach 50 MHz

2 In the “Characteristics” column, bl = bit length, wl = word length, wr = word length relative
3 In the “Expression” column, T
C = 7.5 ns.
4 For the internal clock, the external clock cycle is defined by Icyc and the ESAI control register.
5 The word-relative frame sync signal waveform relative to the clock operates in the same manner as the bit-length frame sync
signal waveform, but spreads starting from one serial clock before the first bit clock (same as the bit length frame sync signal),
until the second-to-last bit-clock of the first word in the frame.
6 Periodically sampled and not 100% tested.
