The IIM provides an interface for reading—and in some cases,
programming, and overriding identification and control
information stored in on-chip fuse elements.

SAHARA2
The JTAGC provides debug access to the ARM926 core,
built-in self-test (BIST), and boundary scan test control.
The KPP is used for key pad matrix scanning or as a general
purpose I/O. This peripheral simplifies the software task of
scanning a keypad matrix.
The LCDC provides display data for external gray-scale or
color LCD panels.
The M3IF controls memory accesses from one or more
masters through different port interfaces to different external
memory controllers ESDCTL/MDDRC, PCMCIA, NFC, and
WEIM.
The ARM926EJ-S processor’s instruction and data buses and
all alternate bus master interfaces arbitrate for resources via a
6 × 3 MAX. There are six fully functional master ports (M0–M5)
and three fully functional slave ports (S0–S2). The MAX is
uni-directional. All master and slave ports are AHB-Lite
compliant.
The MSHC is placed in between the AIPI and the customer
memory stick to support data transfer from the i.MX27 device
to the customer memory stick.
Note: The i.MX27L does not support the MSHC feature
The NFC is a submodule of EMI. The NFC implements the
interface to standard NAND Flash memory devices.
The PCMCIA host adapter module provides the control logic
for PCMCIA socket interfaces, and requires some additional
external analog power switching logic and buffering.
The two DPLLs provide clock generation in digital and mixed
analog/digital chips designed for wireless communication and
other applications.
The PWM has a 16-bit counter and is optimized to generate
sound from stored sample audio images. It can also generate
tones.
