SYSTEM CONTROLLER INTERFACE (I2C BUS)
A fast-mode 400kHz I
2C bus slave interface is used for controlling the 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.

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
5Vand 3V
2
When set, VCC = 3v; when reset, VCC = 5v. When de-activating (setting bit 0 = 0)
and operating with 3V (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

Bits 5 and 6 determine the clock rate to the. See card clock rate selection table
for more details.
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.
