System Controller Interface (I
2C Bus)
A fast-mode 400 kHz I
2C bus slave interface is used for controlling the 73S8010R device and reading the
status of the device via the data pin SDA and clock pin SCL. The bus has 3 address select pins, SAD0,
SAD1, and SAD2. This allows up to 8 devices to be connected in parallel. Table 9 lists the device
address selections for the SAD2:0 settings.

Bit 0 of the I
2C address is the R/W bit. Refer to Figure 5 and Figure 6 for usage.

Description
Start/Stop
0
When set, initiates an activation and a cold reset procedure; when reset,
initiates a deactivation sequence.
Warm reset
1
When set, initiates a warm reset procedure; automatically reset by hardware
when the card starts answering or when the card is declared mute.
5 V and 3 V
2
When set, VCC = 3 V; when reset, VCC = 5 V. When de-activating (setting bit
0 = 0) and operating with 3 V (bit 2 =1), do not simultaneously set bit 2 =0.
Clock Stop
3
When set, the card clock is stopped. Bit 4 determines the card clock stop
level.
Clock Stop Level
4
When set, card clock stops high; when reset card clock stops low.
Clksel1
5
Bits 5 and 6 determine the clock rate to the card. See Table 11 for more
details.
Clksel2
6
I/O enable
7
I/O enable bit. When set, I/O is transferred on I/OUC; when reset I/O to
I/OUC is high impedance.
