(Notes-1) There are some cases where the trace memory capacity varies by a tracing condition or operating status.
(Notes-2) Wait of 1 clock cycle per write of 1 byte.
1.At fixed intervals (IDE feature name "Watch")
Capable of displaying the values of registered variables. The registered variable value display is updated when the target program is stopped, but it is also possible to set to update at constant intervals during program execution.
2.At variable intervals (IDE feature name "Memory Dump")
Capable of displaying all memory contents at variable intervals while running program. The time of reading RAM data might vary by a range of address (number of data) and contents of program.
(Note) Wait of 1 clock cycle per write of 1 byte.
Event comparison/trace memory storage of write operation via stack pointer
Capable of setting data-writing via a stack point as an event comparison target to generate a trigger. By applying this, it is also capable of storing into the trace memory only the data written via the stack pointer. By detecting data-writing to an address other than a pre-assumed stack area, this feature allows you to debug program failures caused by an excessive stack.
Items to Be Prepared by Customer
For In-Circuit Emulation
(Note) A probe set is a product combining a Probe , a Exchange adaptor and a Target connector for each supported MCU.
For On-Chip Debug Emulation
(Notes-1) The on-chip debug function uses two pins for communications (OCDCK, OCDIO) and four pins for monitor signals (VDD, GND, RESET, MODE).
When the On-Chip Debug Emulator is connected to the target system, the OCDCK and OCDIO pins are used exclusively by the Emulator and cannot be used as port pins (P20, P21) or UART0/SIO0 pins.
(Notes-2) For the operation assurance range and characteristics of the supplied power/clock, see the microcomputer's datasheet.

Precautions for USB Connection
To connect the emulator to the target system, solder the target connector to the MCU mounting area on the target system.
For the product specifications of the target connector and the recommended footprints, see ADLINKS Co., Ltd.'s website.
The exchange adapter converts the number of pins and pin layout according to the specifications of the supported MCU. If a corresponding probe set contains the exchange adapter, remember to use it.
For information about the specification of the exchange adapter, please refer to ADLINKS Co., Ltd's website.
MCU mounting adapter
The MCU mounting adapter (Bump socket) is used, together with the target connector, to mount an MCU on the target system. The MCU mounting adapter for the 870/C Light system is manufactured by ADLINKS Co., Ltd. For information about the specification of this product, please refer to ADLINKS Co., Ltd’s website.
