Chapter 7: CSR Accessed From The VMEbus
7.0 Introduction
Chapter 7 describes the VMEbus adapter card Control and Status Registers
(CSR). These registers are accessed by a VMEbus bus master through I/O
space selected with the
I/O HI
and
I/O LO
jumpers on the VMEbus adapter
card.
The base address for accessing the three VMEbus CSRs is set in the
I/O SEL
jumper block on the VMEbus adapter card. These registers are used to
complete the programmed interrupt capabilities between the SBus and the
VMEbus, and to determine if power is on to the SBus adapter card.
7.1 Local Node Registers
The following table shows the location and definition of the VMEbus short
I/O registers. These registers are addressed by processors on the VMEbus.
