4.2.9. Range Compare Control Status Register: ADRCCS0 to
ADRCCS47
The bit configuration of the range compare control status register is shown.
The range compare control status register (ADRCCS) confirms the instruction of the continuous detection
count and the state of the continuous detection count. And, this register selects inside/outside the range
confirmation, range comparison interrupt request enable/disable, range comparison execution
enable/disable, and upper and lower bound threshold.

These bits show the specification of the continuous detection count of the range comparison result and
the state of the continuous detection count.
When the range comparison result reaches the continuous count specification value, "1" is set to the
range comparison interrupt factor flag bit of the corresponding activation channel (ADRCIF.RCINT n).
Moreover, continuous detection stops by the continuous count specification value.
When reading other than read-modify-write (RMW) instruction, state of continuous detection is read.
When read-modify-write (RMW) instruction is read, the writing value (continuous count instruction
value) is read.
