8.3 General subsystem
Address pins on the device are shared with other functions. When connecting external
memories, check that the I/O pin is programmed for the correct function. Control of these
settings is handled by the SCU.
The general subsystem is clocked by CLK_SYS_GESS, see
The key features are:
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 CFID has no external pins.
The SCU takes care of system-related functions.The key feature is configuration of the I/O
port-pins multiplexer.
The SCU defines the function of each I/O pin of the LPC2917/19. The I/O pin
configuration should be consistent with peripheral function usage.
The SCU has no external pins.
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:

Identification of product
Identification of features enabled
Up to 24 level-sensitive external interrupt pins, including CAN, LIN and RXD wake-up
features 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
