Yes -  See the Transputer Data Book 2nd edition p73 (T805)

If BootFromRom is connected high the transputer starts to execute code from
the top two bytes in external memory, at address #7FFFFFFE.  This location should contain a backward jum
should contain a backward jump to a program in ROM.  Following this access, 
BootFromROM may be taken low if required.  The processor is in the low priority state, and the W resty
