16.5: CHKSM Ripple Limit Register
This register is used to determine when the ripple base register overflows to zero. This register forms the
compare value for the ripple base register. When the value of the ripple base register is greater than or equal
to this register, the base register will overflow to zero. For example, when this register is set to four, the ripple
base register would count from zero through four if counting by one.
When set to 0x00, no overflows to zero occur. For example, when the ripple value is 0xff, and you are count-
ing by eight, the next value would still be seven. If counting by one, then the next value would be zero.
This register should be written before the ripple base.

16.6: CHKSM Interrupt Enable Register
Used to specify which status register bits should be used to generate interrupts. See Note on Set/Clear Type
