Range of warranted PLL operation
Notes:
For A/D operating frequency, refer to “5. A/D Converter Electrical Characteristics”
Only at 1 multiplied PLL, use with more than fCP = 4 MHz.
No multiplied
*1 : In setting as 1, 2, 3 and 4 multiplied PLL, when the internal clock is used at 20 MHz < fCP
≤ 25 MHz, set
the PLLOS register to “DIV2 bit
= 1” and “PLL2 bit = 1”.
[Example]
When using the base oscillator frequency of 24 MHz at 1 multiplied PLL :
CKSCR register : CS1 bit
= “0”, CS0 bit = “0”
PLLOS register : PLL2 bit
= “1”
[Example]
When using the base oscillator frequency of 6 MHz at 3 multiplied PLL :
CKSCR register : CS1 bit
= “1”, CS0 bit = “0”
PLLOS register : PLL2 bit
= “1”
*2 : In setting as 2 and 4 multiplied PLL, when the internal clock is used at 20 MHz < fCP
≤ 25 MHz, the following
setting is also enabled.
2 multiplied PLL :
CKSCR register : CS1 bit
= “0”, CS0 bit = “0”
PLLOS register : PLL2 bit
= “1”
4 multiplied PLL :
CKSCR register : CS1 bit
= “0”, CS0 bit = “1”
PLLOS register : PLL2 bit
= “1”
*3 : When using in setting as 6 and 8 multiplied PLL, set the PLLOS register to “DIV2 bit
= 0” and “PLL2 bit = 1”.
[Example]
When using the base oscillator frequency of 4 MHz at 6 multiplied PLL :
CKSCR register : CS1 bit
= “1”, CS0 bit = “0”
PLLOS register : PLL2 bit
= “1”
[Example]
When using the base oscillator frequency of 3 MHz at 8 multiplied PLL :
CKSCR register : CS1 bit
= “1”, CS0 bit = “1”
PLLOS register : PLL2 bit
= “1”
