Objective data sheet
7.34.4 APB interface
7.34.5 AHB multilayer matrix
7.34.6 External interrupt inputs
7.34.7 Memory mapping control
7.35 Emulation and debugging
The APB peripherals are split into two separate APB buses in order to distribute the bus
bandwidth and thereby reducing stalls caused by contention between the CPU and the
GPDMA controller.
The LPC178x/7x 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 (32 kB) static RAM, and the Boot ROM. The GPDMA can also access all of these
memories. Additionally, the matrix connects the CPU system bus and all of the DMA
controllers to the various peripheral functions.
The LPC178x/7x include up to 30 edge sensitive interrupt inputs combined with one level
sensitive external interrupt input as selectable pin function. The external interrupt input
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 LPC178x/7x 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.
