Functional Description and Application Information
2.3.16
Inter IC Communication (I2C)
Inter IC Communication (I2C) is a two-wire, bidirectional serial bus that provides a simple, efficient
method of data exchange, minimizing the interconnection between devices. This bus is suitable for
applications requiring occasional communications over a short distance between many devices. The
flexible I2C enables additional devices to be connected to the bus for expansion and system development.
The I2C operates up to 400 kbps dependent on pad loading and timing. (For pad requirement details, refer
to Phillips I2C Bus Specification, Version 2.1.) The I2C system is a true multiple-master bus, including
arbitration and collision detection that prevents data corruption if multiple devices attempt to control the
bus simultaneously. This feature supports complex applications with multiprocessor control and can be
used for rapid testing and alignment of end products through external connections to an assembly-line
computer.
2.3.17
IC Identification Module (IIM)
The IC Identification Module (IIM) provides an interface for reading and in some cases programming
and/or overriding identification and control information stored in on-chip fuse elements. The module
supports laser fuses (L-Fuses) or electrically-programmable poly fuses (e-Fuses) or both.

IIM, SAHARA2
2.3.18
JTAG Controller (JTAGC)
The JTAG Controller (JTAGC) module supports debug access to the ARM926 Platform and tristate enable
of the I/O pads. The overall strategy is to achieve good test and debug features without increasing the pin
count and reducing the complexity of I/O muxing. The JTAG Controller is compatible with
IEEE Std 1149.1 Standard Test Access Port and Boundary Scan Architecture.
2.3.19
Keypad Port (KPP)
The Keypad Port (KPP) is designed to interface with a keypad matrix with 2-contact or 3-point contact
keys. KPP is designed to simplify the software task of scanning a keypad matrix. With appropriate
software support, the KPP is capable of detecting, debouncing, and decoding one or multiple keys pressed
simultaneously in the keypad. The KPP supports up to 8
× 8 external key pad matrix. Its port pins can be
used as general purpose I/O. Using an open drain design, the KPP includes glitch suppression circuit
design, multiple keys, long key, and standby key detection.
2.3.20
Liquid Crystal Display Controller (LCDC)
The Liquid Crystal Display Controller (LCDC) provides display data for external gray-scale or color LCD
panels. The LCDC is capable of supporting black-and-white, gray-scale, passive-matrix color (passive
color or CSTN), and active-matrix color (active color or TFT) LCD panels.
The LCDC provides the following features:
Configurable AHB bus width (32-bit/64-bit)
