Product data sheet
CAUTION
LPC1751FBD80 with device ID 25001110 does not support CRP feature. LPC1751FBD80 with device ID 25001118 does support
CRP. See errata note in ES_LPC1751.

7.30.3 Code security (Code Read Protection - CRP)
7.30.4 APB interface
The LPC1759/58/56/54/52/51 include 2-stage monitoring of the voltage on the
V
the Vectored Interrupt Controller. This signal can be enabled for interrupt in the Interrupt
Enable Register in the NVIC in order to cause a CPU interrupt; if not, software can monitor
the signal by reading a dedicated status register.
The second stage of low-voltage detection asserts reset to inactivate the
LPC1759/58/56/54/52/51 when the voltage on the V
This reset prevents alteration of the flash as operation of the various elements of the chip
would otherwise become unreliable due to low voltage. The BOD circuit maintains this
reset down below 1 V, at which point the power-on reset circuitry maintains the overall
reset.
Both the 2.2 V and 1.85 V thresholds include some hysteresis. In normal operation, this
hysteresis allows the 2.2 V detection to reliably interrupt, or a regularly executed event
loop to sense the condition.
This feature of the LPC1759/58/56/54/52/51 allows user to enable different levels of
security in the system so that access to the on-chip flash and use of the JTAG and ISP
can be restricted. When needed, CRP is invoked by programming a specific pattern into a
dedicated flash location. IAP commands are not affected by the CRP.
There are three levels of the Code Read Protection.
CRP1 disables access to chip via the JTAG 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 can not be erased.
CRP2 disables access to chip via the JTAG and only allows full flash erase and update
using a reduced set of the ISP commands.
Running an application with level CRP3 selected fully disables any access to chip via the
JTAG pins and the ISP. This mode effectively disables ISP override using P2[10] pin, too.
It is up to the user’s application to provide (if needed) flash update mechanism using IAP
calls or call reinvoke ISP command to enable flash update via UART0.
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.
