EPIT(2)
Enhanced
periodic
interrupt timer
Timer
peripherals
Each Enhanced Periodic Interrupt Timer (EPIT) is a 32-bit set-and-forget
timer that starts counting after the EPIT is enabled by software. It is capable
of providing precise interrupts at regular intervals with minimal processor
intervention. It has a 12-bit prescaler to adjust the input clock frequency to
the required time setting for the interrupts, and the counter value can be
programmed on the fly.
ESAI
Enhanced
serial audio
interface
Connectivity
peripherals
ESAI provides a full-duplex serial port for serial communication with a variety
of serial devices, including industry-standard codecs, SPDIF transceivers,
and other DSPs. The ESAI consists of independent transmitter and receiver
sections, each section with its own clock generator.
eSDHC(2)
Enhanced
multimedia
card/
secure digital
host controller
Connectivity
peripherals
The features of the eSDHC module, when serving as host, include the
following:
Conforms to the SD host controller standard specification version 2.0
Compatible with the JEDEC MMC system specification version 4.2
Compatible with the SD memory card specification version 2.0
Compatible with the SDIO specification version 1.2
Designed to work with SD memory, miniSD memory, SDIO, miniSDIO, SD
combo, MMC and MMC RS cards
Configurable to work in one of the following modes:
—SD/SDIO 1-bit, 4-bit
—MMC 1-bit, 4-bit, 8-bit
Full-/high-speed mode
Host clock frequency variable between 32 kHz and 52 MHz
Up to 200-Mbps data transfer for SD/SDIO cards using four parallel data
lines
Up to 416-Mbps data transfer for MMC cards using eight parallel data lines
FEC
Fast ethernet
controller
Connectivity
peripherals
The Ethernet Media Access Controller (MAC) is designed to support both 10-
and 100-Mbps Ethernet networks compliant with IEEE 802.3 standard. An
external transceiver interface and transceiver function are required to
complete the interface to the media
FlexCAN(2)
Controller
area network
module
Connectivity
peripherals
The Controller Area Network (CAN) protocol is primarily designed to be used
as a vehicle serial data bus running at 1 MBps.
GPIO(4)
General
purpose I/O
modules
System control
peripherals
Used for general purpose input/output to external ICs. Each GPIO module
supports 32 bits of I/O.
GPT(4)
General
purpose
timers
Timer
peripherals
Each GPT is a 32-bit free-running or set-and-forget mode timer with
programmable prescaler and compare and capture register. A timer counter
value can be captured using an external event and can be configured to
trigger a capture event on either the leading or trailing edges of an input
pulse. When the timer is configured to operate in set-and-forget mode, it is
capable of providing precise interrupts at regular intervals with minimal
processor intervention. The counter has output compare logic to provide the
status and interrupt at comparison. This timer can be configured to run either
on an external clock or on an internal clock.
