Connection Of Reset Pin - NEC QB-MINI2 User Manual

CHAPTER 6

6.1.3 Connection of reset pin

This section describes the connection of the reset pin, for which special attention must be paid, in the circuit
connection example shown in the previous section.
During on-chip debugging, a reset signal from the target system is input to MINICUBE2, masked, and then
output to the target device. Therefore, the reset signal connection varies depending on whether MINICUBE2 is
connected.
For flash programming, the circuit must be designed so that the reset signals of the target system and
MINICUBE2 do not conflict.
Select one of the following methods and connect the reset signal in the circuit. The details of each method are
described on the following pages.
(1) Automatically switching the reset signal via series resistor (recommended; described in recommended circuit
connection in the previous section)
(2) Manually switching the reset signal with jumper
(3) Resetting the target device by power-on clear (POC) only
