SPRU748A
Description
Multimedia card interface, compatible with secure digital memory card
interface version 1.0
A generic serial link interface that controls several OMAP5912 external I
slave devices or slaves them to other OMAP5912 external I
devices
A master/slave serial port interface, running up to 19.2M bits/s in master or
slave mode
All of these general-purpose timers can be configured to count either from
the 32-kHz clock or from the system clock. Three of them are also used to
provide two PWM signals at the OMAP5912 boundary.
Used as communication processor data interface or I2S emulator
A UART modem including autobaud. The maximum baud rate is 3.6M bits/s.
A UART modem with autobaud, as in UART1
A UART IrDA enabling slow, medium, and fast configurations
Each host peripheral access can be configured by software as the DSP or the
MPU for each peripheral.
Description
There are four instances of 16-bit module general-purpose I/Os. Each
module can generate its own interrupt. Several general-purpose I/Os are
multiplexed with primary I/Os, some of which are connected directly with
dedicated I/Os.
This is a simple upward counter clock used by the 32-kHz input clock to
enable synchronization between modem and application chips when
OMAP5912 is used in conjunction with a modem having the same clock
input. As soon as the power-up reset input is released, the counter starts
counting.
Each host peripheral access can be either the DSP or the MPU; the arbitration
is performed in hardware.
Table 7 lists the dedicated modules available in OMAP5912, a general
description of each module, and their corresponding functional specifications
reference.
