Description
PLL clock
Normal runThe CPU and peripheral resources operate at the clock frequency obtained by PLL
multiplication of oscillator clock (HCLK) frequency.
Sleep
Only peripheral resources operate at the clock frequency obtained by PLL multiplica-
tion of the oscillator clock (HCLK) .
Time-base
timer
Only the time-base timer operates at the clock frequency obtained by PLL multiplica-
tion of the oscillator clock (HCLK) frequency.
Stop
The CPU and peripheral resources are suspended with the oscillator clock stopped.
Main clock
Normal runThe CPU and peripheral resources operate at the clock frequency obtained by divid-
ing the oscillator clock (HCLK) frequency by two.
Sleep
Only peripheral resources operate at the clock frequency obtained by dividing the
oscillator clock (HCLK) frequency by two.
Time-base
timer
Only the time-base timer operates at the clock frequency obtained by dividing the
oscillator clock (HCLK) frequency by two.
Stop
The CPU and peripheral resources are suspended with the oscillator clock stopped.
Sub clock
Normal runThe CPU and peripheral resources operate at the clock frequency obtained by
dividing the subclock (SCLK) frequency by four.
Sleep
Only peripheral resources operate at the clock frequency obtained by dividing the
subclock (SCLK) frequency by four.
Watch
mode
Only the watch timer operates at the clock frequency obtained by dividing the
subclock (SCLK) frequency by four.
Stop
The CPU and peripheral resources are suspended with the subclock stopped.
CPU
intermittent
operation
mode
Normal runThe halved or PLL-multiplied oscillator clock (HCLK) frequency or the subclock
(SCLK) frequency is used for operation while being decimated in a certain period.
