The processor asserts BG as soon as possible after receipt of BR. This is
immediately following internal synchronization except during a read-modify-
write cycle or following an internal decision to execute a bus cycle. During
a read-modify-write cycle, the processor does not assert BG until the entire
operation has completed. RMC is asserted to indicate that the bus is locked,
in the case an internal decision to execute another bus cycle, BG is deferred
until the bus cycle has begun.
