7.31 Emulation and debugging
The LPC1768/66/65/64 use an AHB multilayer matrix. This matrix connects the instruction
(I-code) and data (D-code) CPU buses of the ARM Cortex-M3 to the flash memory, the
main (32KB) static RAM, and the Boot ROM. The GPDMA can also access all of these
memories. The peripheral DMA controllers, Ethernet (LPC1768/66/64 only) and USB, can
access all SRAM blocks. Additionally, the matrix connects the CPU system bus and all of
the DMA controllers to the various peripheral functions.
The LPC1768/66/65/64 include up to 46 edge sensitive interrupt inputs combined with up
to four level sensitive external interrupt inputs as selectable pin functions. The external
interrupt inputs can optionally be used to wake up the processor from Power-down mode.
The Cortex-M3 incorporates a mechanism that allows remapping the interrupt vector table
to alternate locations in the memory map. This is controlled via the Vector Table Offset
Register contained in the NVIC.
The vector table may be located anywhere within the bottom 1 GB of Cortex-M3 address
space. The vector table must be located on a 128 word (512 byte) boundary because the
NVIC on the LPC1768/66/65/64 is configured for 128 total interrupts.
Debug and trace functions are integrated into the ARM Cortex-M3. Serial wire debug and
trace functions are supported in addition to a standard JTAG debug and parallel trace
functions. The ARM Cortex-M3 is configured to support up to eight breakpoints and four
watch points.
