20.2.1
The access size must be the same as the control register size. If the sizes are different, a write will
not be effected in a UBC register write operation, and a read operation will return an undefined
value. UBC control register contents cannot be transferred to a floating-point register using a
floating-point memory load instruction.
When a UBC control register is updated, use either of the following methods to make the updated
value valid:
1. Execute an RTE instruction after the memory store instruction that updated the register. The
2. Execute instructions requiring 5 states for execution after the memory store instruction that

updated the register. As the CPU executes two instructions in parallel and a minimum of 0.5
state is required for execution of one instruction, 11 instructions must be inserted. The updated
value will be valid from the 6th state onward.
