Subsystem
The IIM provides the primary user-visible mechanism for interfacing
with on-chip fuse elements. Among the uses for the fuses are unique
chip identifiers, mask revision numbers, cryptographic keys, and
various control signals requiring a fixed value.
Each I/O multiplexer provides a flexible, scalable multiplexing
solution with the following features:
Up to eight output sources multiplexed per pin
Up to four destinations for each input pin
Unselected input paths held at constant levels for reduced power
consumption
The IPU supports video and graphics processing functions. It also
provides the interface for image sensors and displays. The IPU
performs the following main functions:
Preprocessing of data from the sensor or from the external system
memory
Postprocessing of data from the external system memory
Post-filtering of data from the system memory with support of the
MPEG-4 (both deblocking and deringing) and H.264 post-filtering
algorithms
Displaying video and graphics on a synchronous (dumb or
memory-less) display
Displaying video and graphics on an asynchronous (smart) display
Transferring data between IPU sub-modules and to/from the system
memory with flexible pixel reformatting
Can be used for either keypad matrix scanning or general purpose
I/O.
The MLB is designed to interface to an automotive MOST ring.
The OSCAUDIO oscillator provides a stable frequency reference for
the PLLs. This oscillator is designed to work in conjunction with an
external 24.576-MHz crystal.
The signal from the external 24-MHz crystal is the source of the
CLK24M signal fed into USB PHY as the reference clock and to the
real time clock (RTC).
MCU PLL (MPLL)—programmable
Peripheral PLL (PPLL)—programmable
The pulse-width modulator (PWM) is optimized to generate sound
from stored sample audio images; it can also generate tones.
Provides the ARM1136 platform with a clock function (days, hours,
minutes, seconds) and includes alarm, sampling timer, and minute
stopwatch capabilities.
DPLLs are used to generate the clocks:
