+USB Interface:

+Vusb, P0.26, P0.27
+
+Serial Console:
+===============
+
+Both UART0 and UART1 are always enabled.  UART0 is configured to be the
+serial console in these configurations.
+
+P0.0/TXD0/PWM1        Module Socket, Pin 4
+P0.1/RxD0/PWM3/EINT0  Module Socket, Pin 5
+
+P0.8/TXD1/PWM4/AD1.1  Module Socket, Pin 12
+P0.9/RxD1/PWM6/EINT3  Module Socket, Pin 13
+
+Configurations:
+===============
+
+Each NXP LPC214x configuration is maintained in a sudirectory and
+can be selected as follow:
+
+    cd tools
+    ./configure.sh zp214xpa/<subdir>
+    cd -
+    . ./setenv.sh
+
+Where <subdir> is one of the following:
+
+nsh:
+----
+
+  Configures the NuttShell (nsh) located at examples/nsh.  The
+  Configuration enables only the serial NSH interfaces.
+
+    NOTES:
+ 
+    1. This configuration uses the mconf-based configuration tool.  To
+       change this configuration using that tool, you should:
+
+       a. Build and install the mconf tool.  See nuttx/README.txt and
+          misc/tools/
+
+       b. Execute 'make menuconfig' in nuttx/ in order to start the
+          reconfiguration process.
+
+    2. Default platform/toolchain:
+
+       CONFIG_HOST_LINUX=y             : Windows
+       CONFIG_ARM_TOOLCHAIN_GNU_EABI=y : Buildroot (arm-nuttx-elf-gcc)
+       CONFIG_RAW_BINARY=y             : Output formats: ELF and raw binary
