3.1.6 Extension Connectors (J9-J13)

The M3A-HS49 includes extension connectors to which the I/O pins of the SH7149 are connected.

MIL Standard connectors can be connected to J9-J13, allowing the user to create extension board or monitor the

SH7149 bus signals.

The bus signals of SH7149 are connected to the terminal connector J10 (J13) through J9 (J12). There are J9 and

J12 for measuring the signals by measuring instrument. When an extension board is made, J10 and J13 of the

terminal connector are recommended to be used to prevent the waveform being distorted because of the reflection of

the signal.

Figure3.1.8 shows a pin assignment of extension connector.
