The FLMD0 signal is not required, if the N-Wire debugger serves the FLMD0 signal internally by using the
SELFEN register to enable flash self-programming (refer to “Flash Self-Programming” on page 234). Howev-
er the FLMD0 signal may be connected.

Pin functions
The following table shows the pin functions of the connector for emulator
connection (target system side). “I/O” indicates the direction viewed from the
device.

Preliminary User’s Manual U17566EE1V2UM00
The connection of the pins not supported by the microcontroller is
dependent upon the emulator to be used.
The pattern of the target board must satisfy the following conditions.

On-chip debug unit reset input
Reset input. (In a system that uses only POC reset and not pin
reset, some emulators input an external reset signal as shown in
Figure 28-6 on page 889 to set the OCDM0 bit to 1.)
