6.19.4
External interrupt inputs
The LPC2210 includes up to nine edge or level sensitive External Interrupt Inputs as
selectable pin functions. When the pins are combined, external events can be
processed as four independent interrupt signals. The External Interrupt Inputs can
optionally be used to wake up the processor from Power-down mode.
6.19.5
Memory Mapping Control
The Memory Mapping Control alters the mapping of the interrupt vectors that appear
beginning at address 0x00000000. Vectors may be mapped to the bottom of the
BANK0 external memory, or to the on-chip static RAM. This allows code running in
different memory spaces to have control of the interrupts.
6.19.6
Power Control
The LPC2210 supports two reduced power modes: Idle mode and Power-down
mode. In Idle mode, execution of instructions is suspended until either a Reset or
interrupt occurs. Peripheral functions continue operation during Idle mode and may
generate interrupts to cause the processor to resume execution. Idle mode eliminates
power used by the processor itself, memory systems and related controllers, and
internal buses.
In Power-down mode, the oscillator is shut down and the chip receives no internal
clocks. The processor state and registers, peripheral registers, and internal SRAM
values are preserved throughout Power-down mode and the logic levels of chip
output pins remain static. The Power-down mode can be terminated and normal
operation resumed by either a Reset or certain specific interrupts that are able to
function without clocks. Since all dynamic operation of the chip is suspended,
Power-down mode reduces chip power consumption to nearly zero.
A Power Control for Peripherals feature allows individual peripherals to be turned off if
they are not needed in the application, resulting in additional power savings.
6.19.7
VPB bus
The VPB Divider determines the relationship between the processor clock (cclk) and
the clock used by peripheral devices (PCLK). The VPB Divider serves two purposes.
The first is that the VPB bus cannot operate at the highest speeds of the CPU. In
order to compensate for this, the VPB bus may be slowed down to one half or one
fourth of the processor clock rate. The default condition at reset is for the VPB bus to
run at one quarter of the CPU clock. The second purpose of the VPB Divider is to
allow power savings when an application does not require any peripherals to run at
the full processor rate. Because the VPB Divider is connected to the PLL output, the
PLL remains active (if it was running) during Idle mode.
6.20 Emulation and debugging
The LPC2210 supports emulation and debugging via a JTAG serial port. A trace port
allows tracing program execution. Debugging and trace functions are multiplexed only
with GPIOs on Port 1. This means that all communication, timer and interface
peripherals residing on Port 0 are available during the development and debugging
phase as they are when the application is run in the embedded system itself.
