unmask Enable the accepting of an interrupt by the CPU
wait state Additional T-states that may be added to a
memory access to increase the time from address genera-
tion to the beginning of either a memory read or write The
BCP may add as many as seven data wait states and three
instruction wait states
X-TCLK The eXternal Transceiver CLocK An indepen-
dent clock source that the BCP transceiver operation may
synchronize to rather than from OCLK
support device or system whose failure to perform can
be reasonably expected to cause the failure of the life
support device or system or to affect its safety or
effectiveness
