Keysight E1458A Register Information

Register Definitions

You can program the Keysight E1458A 96-Channel Digital I/O Module using its
hardware registers. The procedures for reading or writing to a register depend on
your operating system and programming language. Whatever the access
method, you will need to identify each register with its address. These addresses
are given in Table B - 2.
The module is a register-based slave/interrupter device, supporting VME D16,
D8(O), and D8(OE) transfers. The interrupt protocol supported is "release on
interrupt acknowledge" – an interrupt is cleared by a VXIbus interrupt
acknowledge cycle.
