In relative mode, the set value of high-speed counting 100 segments is relative cumulative
value. When the set value of counting equals the sum of the interruption count value of N-1
segment and the set value of N segment, the segment N interrupt is generated.
N interrupt markers correspond to N interrupt settings. The N+1 interrupt settings register is
reserved for other purposes.
Example1:
The current value of HSC0 is 0, segment one preset value is 10000, the preset value in
segment 2 is －5000, the preset value in segment 3 is 20000. When starting to count, when
the counter's current value is 10000, it generates the segment 1 interruption I2000; when the
counter's current value is 5000, it generates the segment 2 interruption I2001; when the
counter's current value is 25000, it generates the segment 3 interruption I2002.
See graph below:

K0
HSC0= K0+K10000=K10000
HSC0= K10000+（K-5000）=K5000
Example 2:
HSC2 current value is 10000, the segment one preset value is 10000, the preset value of
segment 2 is 5000, the preset value of segment 3 is 20000. When starting to count, when the
counter's current value is 20000, it generates the segment 1 interruption I2100; when the
counter's current value is 25000, it generates the segment 2 interruption I2101; when the
counter's current value is 45000, it generates the segment 3 interruption I2102.
