Description
Noise Elimination Sampling Frequency Select
Selects the frequency by which the subclock ( SUB) input
from the EXCL pin is sampled using the clock ( ) generated
by the system clock pulse generator. Clear this bit to 0
when
0: Sampling using /32 clock
1: Sampling using /4 clock
Subclock Input Enable
Enables/disables subclock input from the EXCL pin.
0: Disables subclock input from the EXCL pin
1: Enables subclock input from the EXCL pin
Reserved
An undefined value is read from this bit. This bit should not
be set to 1.
Reserved
These bits are always read as 0 and cannot be modified.
