Note:
Bit 6—Low-Speed On Flag (LSON): Determines the operating mode in combination with other
control bits when making a power-down transition by executing a SLEEP instruction. Also
controls whether a transition is made to high-speed mode or to subactive mode when watch mode
is cleared.

Note:
Bit 5—Noise Elimination Sampling Frequency Select (NESEL): Selects the frequency at which
the subclock ( SUB) input from the EXCL pin is sampled with the clock ( ) generated by the
system clock oscillator. When = 5 MHz or higher, clear this bit to 0.

Description
When a SLEEP instruction is executed in high-speed mode or medium-speed mode,
a transition is made to sleep mode, software standby mode, or watch mode *
When a SLEEP instruction is executed in subactive mode, a transition is made to
subsleep mode or watch mode
When a SLEEP instruction is executed in high-speed mode or medium-speed mode,
a transition is made directly to subactive mode * , or a transition is made to sleep mode
or software standby mode
When a SLEEP instruction is executed in subactive mode, a transition is made directly
