Bit 5—Noise Elimination Sampling Frequency Select (NESEL): This bit selects the sampling
frequency of the subclock (øSUB) generated by the subclock oscillator is sampled by the clock (ø)
generated by the system clock oscillator. Set this bit to 0 when ø=5MHz or more.
Bit 5
NESEL
Description
0
Sampling using 1/32 xø
1
Sampling using 1/4 xø
Bit 4—Subclock enable (SUBSTP): This bit enables/disables subclock generation.
Bit 4
SUBSTP Description
0
Enables subclock generation
1
Disables subclock generation
Bit 3—Oscillation Circuit Feedback Resistance Control Bit (RFCUT): This bit turns the
internal feedback resistance of the main clock oscillation circuit ON/OFF.
Bit 3
RFCUT
Description
0
When the main clock is oscillating, sets the feedback resistance ON. When the main
clock is stopped, sets the feedback resistance OFF.
1
Sets the feedback resistance OFF.
Bit 2—Reserved: Should always be written with 0.
