4.3 Pin Termination

(1) MODE0 to MODE3 pins
When the emulator operates as a stand-alone unit, the operation mode of the emulator is single-chip mode 0.
The MODE0 to MODE3 pins are connected as follows.
•
MODE0: Connected to V
•
MODE1: Connected to V
•
MODE2: Unconnected
•
MODE3: Unconnected
(2) RESET pin
This pin is connected to V
(3) CKSEL pin
Pull-up/pull-down switching is possible with SW1.
