Figure 34. Clock Set Up Sequence(2)
<Example>
(1) Release the pull-down of the XTI pin : MCKPD bit = “1”
→
“0” and and power-up the X’tal oscillator: PMXTL
bit = “0”
→
“1”
(2) Power-up PLL : PMPLL bit = “0”
→
“1”
The PLL should be powered-up after the X’tal oscillator becomes stable. If X'tal and PLL are powered-up at the
same time, the PLL does not start. It takes X’tal oscillator 20ms(typ) to be stable after PMXTL bit=“1”. This
time depends on X’tal. PLL needs 40ms lock time the PMPLL bit = “0”
→
“1”.
(3) Enable MCKO output : MCKO bit = “0”
→
“1” and set up MCKO output frequency (PS1-0 bits)
(4) MCKO, BICK and LRCK are output after PLL lock time.
