Reset Outputs
— VMEbus System Reset Out (SRSTO): This signal is used to reset the VMEbus.
— Local Bus (PCI/X) Reset Out (LRSTO_): This signal resets local (PCI/X) resources.
Typically, this signal is connected to the backplane SYSRESET_ signal through an
inverting open collector buffer. When SRSTO is asserted, the VMEbus SYSRESET_
signal is asserted.
SRSTO can be asserted either through hardware or software events. The hardware
reset events are detailed in
setting the SRESET bit in the VMEbus Control (VCTRL) register (see
Section 10.4.34 on page
The SRESET bit is self-clearing if SRSTI is connected to SRSTO through a
transceiver.
LRSTO_ can be combined with other board sources to generate a local (PCI/X) reset
signal.
LRSTO_ can be asserted either through hardware or software events. The hardware
reset events are detailed in
by the following methods:
If the SRESET bit is set, the Tsi148 asserts SRSTO output even if it is not the
system controller.
The SRSTO signal is asserted for a minimum of 200ms.
