12.7.9
When the GM bit in SMR is set to 1, the clock output level can be fixed with bits CKE0 and CKE1
in SCR. At this time, the minimum clock pulse width can be made the specified width. Figure
12.34 shows the timing for fixing the clock output level. In this example, GM is set to 1, CKE1 is
cleared to 0, and the CKE0 bit is controlled.
