Buffer transfer at transition from up-counting to down-counting
If the general register value is in the range from GRA3 – T + 1 to GRA3, do not transfer a
buffer register value outside this range. Conversely, if the general register value is outside
this range, do not transfer a value within this range. See figure 10.40.
Buffer transfer at transition from down-counting to up-counting
If the general register value is in the range from H'0000 to T – 1, do not transfer a buffer
register value outside this range. Conversely, when a general register value is outside this
range, do not transfer a value within this range. See figure 10.41.
