(Factory-setting)
4.8 V ≤ VCC1 ≤ 5.2 V and 3.3 V ≤ VCC2 < VCC1
Connects pins AVCC and AVSS of the MCU to the
AVCC
target system.
AVSS EXT INT
(Factory-setting)
Connects pin AVCC of the MCU to the internal
power supply of the emulator, and connects pin
AVSS to the GND in the emulator.
AVCC
AVSS EXT INT
Connects pin P87 of the MCU to the target system.
P87 XCIN VCONT
(Factory-setting)
