The ARM Cortex-M0 is a general purpose, 32-bit microprocessor, which offers high
performance and very low power consumption.
The ARM Cortex-M0 includes a System Tick timer (SYSTICK) that is intended to generate
a dedicated SYSTICK exception at a 10 ms interval.
The LPC122x contain up to 128 kB of on-chip flash memory.
The LPC122x contain a total of up to 8 kB on-chip static RAM memory.
The LPC122x incorporates several distinct memory regions, shown in the following
figures.
program viewpoint following reset. The interrupt vector area supports address remapping.
The AHB peripheral area is 2 megabyte in size, and is divided to allow for up to 128
peripherals. The APB peripheral area is 512 kB in size and is divided to allow for up to 32
peripherals. Each peripheral of either type is allocated 16 kilobytes of space. This allows
simplifying the address decoding for each peripheral.
