Clock output can be fixed using the CKE1 and CKE0 bits in SCR when the GM bit in SMR is set
to 1. Specifically, the minimum width of a clock pulse can be specified.
Figure 14.31 shows an example of clock output fixing timing when the CKE0 bit is controlled
with GM = 1 and CKE1 = 0.
At power-on and transitions to/from software standby mode, use the following procedure to secure
the appropriate clock duty cycle.
