Notes:
1. When V
IO
= 0 V, SCLK and SDIO are low-impedance. 2-wire control interface is I
2
C compatible.
2. When selecting 2-wire mode, the user must ensure that a 2-wire start condition (falling edge of SDIO while SCLK is
high) does not occur within 300 ns before the rising edge of RST
.
3. When selecting 2-wire mode, the user must ensure that SCLK is high during the rising edge of RST
, and stays high
until after the first start condition.
4. The Si4712/13 delays SDIO by a minimum of 300 ns from the V
IH
threshold of SCLK to comply with the minimum
t
HD:DAT
specification.
5. The maximum t
HD:DAT
has only to be met when f
SCL
= 400 kHz. At frequencies below 400 KHz, t
HD:DAT
may be
violated as long as all other timing parameters are met.
