Table 3. Digital and Analog Modules
The 1-Wire module provides bi-directional communication between
the ARM11 core and external 1-Wire devices.
The ATA block is an AT attachment host interface. It is designed to
interface with IDE hard disc drives and ATAPI optical disc drives.
The AUDMUX interconnections allow multiple, simultaneous
audio/voice/data flows between the ports in point-to-point or
point-to-multipoint configurations.
The CAMP converts a square wave/sinusoidal input into a rail-to-rail
square wave. The output of CAMP feeds the predivider.
The CCM provides clock, reset, and power management control for
the MCIMX31.
The CSPI is equipped with data FIFOs and is a master/slave
configurable serial peripheral interface module, capable of
interfacing to both SPI master and slave devices.
The DPLLs produce high-frequency on-chip clocks with low
frequency and phase jitters.
Note: External clock sources provide the reference frequencies.
The ECT is composed of three CTIs (Cross Trigger Interface) and
one CTM (Cross Trigger Matrix—key in the multi-core and
multi-peripheral debug strategy.
The EMI includes
The EPIT is a 32-bit “set and forget” timer which starts counting after
the EPIT is enabled by software. It is capable of providing precise
interrupts at regular intervals with minimal processor intervention.
tracing by way of ETM auxiliary I/O port.
This FIR is capable of establishing a 0.576 Mbit/s, 1.152 Mbit/s or 4
Mbit/s half duplex link via a LED and IR detector. It supports 0.576
Mbit/s, 1.152 Mbit/s medium infrared (MIR) physical layer protocol
and 4Mbit/s fast infrared (FIR) physical layer protocol defined by
IrDA, Rev. 1.4.
