I

C-bus interface
A simple I
2
C-bus interface is provided in the ISP1561 to read customized vendor ID,
product ID and some other configuration bits from an external EEPROM.
The I
2
C-bus interface is intended for bidirectional communication between ICs via two
serial bus wires, SDA (data) and SCL (clock). Both lines are driven by open-drain
circuits and must be connected to the positive supply voltage via pull-up resistors.
9.1 Protocol
The I
2
C-bus protocol defines the following conditions:
Bus free
: both SDA and SCL are HIGH
START
: a HIGH-to-LOW transition on SDA, while SCL is HIGH
STOP
: a LOW-to-HIGH transition on SDA, while SCL is HIGH
Data valid
: after a START condition, data on SDA are stable during the HIGH
period of SCL; data on SDA may only change while SCL is LOW.
Each device on the I
2
C-bus has a unique slave address, which the master uses to
select a device for access.
The master starts a data transfer using a START condition and ends it by generating
a STOP condition. Transfers can only be initiated when the bus is free. The receiver
must acknowledge each byte by means of a LOW level on SDA during the ninth clock
pulse on SCL.
For detailed information please consult The I
2
C-bus and how to use it, order number
9398 393 40011.
9.2 Hardware connections
Via the I
2
C-bus interface the ISP1561 can be connected to an external EEPROM.
The hardware connections are shown in
