RESET VMEbus ADAPTOR CARD (bit 7): The VMEbus adapter card has a
power-on-reset circuit. The adapter card may also be reset from the
SPARCstation by writing a "1" to this bit. After triggering the reset, your
program should wait one second before starting another remote access or
VMEbus cycle.
This resets only the adapter card, unless the VMEbus adapter card
SYSRESET
jumper that drives the VMEbus global reset signal in system
controller configuration is installed. See section 4.4.
Writing a "0" to bit 7 clears the
VMEbus Was Reset
flag in the Remote
Status Register.
If the
SYSRESET
jumper in the
SYS
jumper block is installed, this reset
also drives the VMEbus global reset signal. See section 4.4 for more
information about the
SYS
jumper block.
CLEAR PT INTERRUPT (bit 6): If a VMEbus processor sets the PT Interrupt
flip-flop on the VMEbus adapter card, a SBus processor can clear it by writing
a "1" to this bit.
SET PR INTERRUPT (bit 5): A SBus processor sends a PR Interrupt to the
VMEbus chassis by writing a "1" to bit 5 (sets the PR flip-flop on the VMEbus
adapter card). Writing a "0" clears the PR Interrupt. The PR Interrupt must
be enabled in the VMEbus adapter card
R-INT
jumper block. See section 4.6.
