LPC11U2x
32-bit ARM Cortex-M0 microcontroller
1. CRP1 disables access to the chip via the SWD and allows partial flash update
(excluding flash sector 0) using a limited set of the ISP commands. This mode is
useful when CRP is required and flash field updates are needed but all sectors cannot
be erased.
2. CRP2 disables access to the chip via the SWD and only allows full flash erase and
update using a reduced set of the ISP commands.
3. Running an application with level CRP3 selected, fully disables any access to the chip
via the SWD pins and the ISP. This mode effectively disables ISP override using
PIO0_1 pin as well. If necessary, the application must provide a flash update
mechanism using IAP calls or using a call to the reinvoke ISP command to enable
flash update via the USART.
In addition to the three CRP levels, sampling of pin PIO0_1 for valid user code can be
disabled. For details, see the LPC11Uxx user manual.
7.17.6.4
APB interface
The APB peripherals are located on one APB bus.
7.17.6.5
AHBLite
The AHBLite connects the CPU bus of the ARM Cortex-M0 to the flash memory, the main
static RAM, and the ROM.
7.17.6.6
External interrupt inputs
All GPIO pins can be level or edge sensitive interrupt inputs.
CAUTION
If level three Code Read Protection (CRP3) is selected, no future factory testing can be
performed on the device.
