Bit 3—Low Speed on Flag (LSON): This bit chooses the system clock ( ) or subclock (
the CPU operating clock when watch mode is cleared. The resulting operation mode depends on
the combination of other control bits and interrupt input.

Bits 2 to 0—Reserved Bits: These bits are reserved; they are always read as 1, and cannot be
modified.
System Control Register 2 (SYSCR2)
SYSCR2 is an 8-bit read/write register for power-down mode control.
Bits 7 to 5—Reserved Bits: These bits are reserved; they are always read as 1, and cannot be
modified.
Bit 4—Noise Elimination Sampling Frequency Select (NESEL): This bit selects the frequency
at which the watch clock signal (
relation to the oscillator clock (
2 to 10 MHz, clear NESEL to 0.
