2. 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 (ø
generator is sampled, in relation to the oscillator clock (ø
generator. When ø
