13. Code Size Assuming Keil MDK compilation result is
Program Size: Code=3696 RO-data=2256 RW-data=60 ZI-data=1348  
Code : program code (程式碼)
RO-data : Read-Only Data (唯讀資料)
RW-data : Read/Write Data (讀寫資料)
ZI-data : Zero Initialized Data (初始為0的資料)
Then
Total ROM size = Code + RO-data + RW-data = = 6012 Bytes
Total RAM size = RW-data + ZI-data = = 1408 Bytes
* Nano102的 ROM size = 32K Bytes, RAM size = 16K Bytes
* Evaluation License limit code size at 32KB

32. ARM CoreSight Technology
ARM Cortex-M processor-based devices use the ARM CoreSight technology which introduces powerful new debug and trace capabilities
Debug Features:
Run Control of the processor allowing you to start and stop programs
Single Step one source or assembler line
Set breakpoints while the processor is running
Read/write memory contents and peripheral registers on-the-fly
Program internal and external FLASH memory
Trace Features:
Serial Wire Viewer (SWV) provides program counter (PC) sampling, data trace, event trace, and instrumentation trace information
Instruction (ETM) Trace streamed directly to your PC enabling debugging of historical sequences, software profiling, and code coverage analysis

33. CoreSight Block Diagram

34. SWD (Serial Wire Debug)
The SWD interface pins can be overlaid with JTAG signals, allowing the standard target connectors to be used:
TCLK - SWCLK (Serial Wire Clock)
TMS - SWDIO (Serial Wire Data Input/Output)
TDO - SWO (Serial Wire Output - required for SWV)
JTAG and SWD modes are fully supported by ULINK2, ULINK-ME, and ULINKpro.
Nu-Link ICE signals :
VCC
ICE_DAT
ICE_CLK
RST
GND

39. Setup ISP mode
Step 1. use ICP tool to upload MCU’s LDROM code for ISP mode (ICP tool use Nu-Link to upload LDROM)
Step 2. run Keil MDK to build a project for MCU binary file
Step 3. connect USB-to-UART comm port to Nu-LB-NUC140 UART TX/RX pins (used by LDROM code)
Step 4. run ISP tool to download binary into MCU
