ARM9 microcontroller with CAN, LIN, and USB
6.11 General subsystem
6.11.1
General subsystem clock description
The general subsystem is clocked by CLK_SYS_GESS, see
Section 6.7.2
.
6.11.2
Chip and feature identification
The Chip/Feature ID (CFID) module contains registers which show and control the
functionality of the chip. It contains an ID to identify the silicon and also registers
containing information about the features enabled or disabled on the chip.
The key features are:
Identification of product
Identification of features enabled
The CFID has no external pins.
6.11.3
System Control Unit (SCU)
The system control unit contains system-related functions.The key feature is configuration
of the I/O port-pins multiplexer. It defines the function of each I/O pin of the
LPC2921/2923/2925. The I/O pin configuration should be consistent with peripheral
function usage.
The SCU has no external pins.
6.11.4
Event router
The event router provides bus-controlled routing of input events to the vectored interrupt
controller for use as interrupt or wake-up signals.
Key features:
Up to 16 level-sensitive external interrupt pins, including the receive pins of SPI, CAN,
LIN, and UART, as well as the I
2
C-bus SCL pins plus three internal event sources.
Input events can be used as interrupt source either directly or latched
(edge-detected).
Direct events disappear when the event becomes inactive.
Latched events remain active until they are explicitly cleared.
Programmable input level and edge polarity.
Event detection maskable.
Event detection is fully asynchronous, so no clock is required.
The event router allows the event source to be defined, its polarity and activation type to
be selected and the interrupt to be masked or enabled. The event router can be used to
start a clock on an external event.
The vectored interrupt-controller inputs are active HIGH.
