DWMBB Adapter
3.6.5 Programmable Lockout Limit
Software loads the Lockout Limit field (AUTLR<31:28>) with a value
that determines the number of IREAD transactions attempted by the
DWMBB before it asserts the XMI LOCKOUT L signal. When the number
of consecutive IREAD attempts on the VAXBI equals or exceeds the value
in this field, the DWMBB asserts the XMI LOCKOUT L signal. Table 3–6
lists the values for this field.
