Clock Output Control
When the GM bit in SMR is set to 1, the clock output level can be fixed with the CKE1 and CKE0
bits in SCR. At this time, the minimum clock pulse width can be specified.
Figure 13.29 shows the timing for fixing the clock output level. In this example, the GM bit is set
to 1, the CKE1 bit is cleared to 0, and the CKE0 bit is controlled.
