1.4.2 Size of the Address Range
The size of the address range occupied by the ES1650.1 Piggyback Carrier
Board in your system is selected by jumper B16. You can choose between the
sizes 265 bytes and 8 KBytes. The size that needs to be set depends on the
piggybacks used.
1.4.3 Address Modifier
The B3 jumper determines the address modifier. You can choose between the
access types "Short Access" (29/2D) and "Standard Access" (39/3D/00)
1.4.4 Local Reset
You can trigger a local reset of the piggybacks by using an external connector
pin on the front panel. Use jumper B20 to specify whether this external con-
nector pin is to be evaluated.
