3.5.17Flash Bank A Write Protect Header

A 2-pin 2 mm header is located on the board to enable/disable programming of Flash Bank A to protect the contents from being corrupted. No jumper installed disables all Flash Bank A programming by driving the FLASH VPEN pin to a logic low. The jumper must be installed for erasing array blocks, programming data or configuring lock-bits. The pin assignments for this header are as follows:

3.5.18+/-12 V Present Header

A 2-pin 0.1" header is located on the board to inform the CPCI-6115 whether the +/-12 V power supplies are present on the backplane. If so, then these power supplies are monitored for inclusion in the HLTY# status. If no jumper is installed, the CPCI-6115 will assume that the +/- 12 V supplies are present. With a jumper installed, the +/-12 V power supplies are not monitored. The pin assignments for this header are as follows:
