Note 1. t_Pcyc: PCLK cycle
Note 2. t_cac: CAC count clock source cycle
Note 3. When the LOCO is selected as the clock output source (CKOCR.CKOSEL[2:0] bits = 000b), set the clock output division ratio
selection to divided by 2 (CKOCR.CKODIV[2:0] bits = 001b).
Note 4. When the XTAL external clock input or an oscillator is used with divided by 1 (CKOCR.CKOSEL[2:0] bits = 010b and
CKOCR.CKODIV[2:0] bits = 000b) to output from CLKOUT, the above should be satisfied with an input duty cycle of 45 to 55%.
