4.7. VME operations
The VSBC-6862 includes also modules to handle VME operations.
There is VME master, slave, interrupter, interrupt-handler and system controller modules.
Each module can be considered as an independent module.
The next chapters will describe these modules.
4.7.1. Jumpers
Some functions are controlled by jumpers for the VME module.
The first jumpers block controls generic master purposes:
The main function is to set the SLOT1 function that activates the VME controller when the
VSBC-6862 is plugged in the slot1.
See jumper 'Slot1' description.
The other functions are for Reset operations between VME and the VSBC-6862. These
functions are described in the above corresponding chapter.
See jumpers 'Sysresetin' and 'Sysresetout' description.
The second jumpers block sets the base address of the slave VME registers.
See the 'Jumper 8' description
4.7.2. Registers
The VSBC-6862 contains registers to configure the VME operations.
These registers are controlled by the Chip Select 4.
