In addition, the following data is stored for the comparison table:
DM 0000 0002 Number of comparison conditions: 2
DM 0001 1000 Target value 1: 1000
DM 0002 0000
DM 0003 0101 Comparison 1 interrupt processing routine no.: 101
DM 0004 2000 Target value 1: 2000
DM 0005 0000
DM 0006 0102 Comparison 2 interrupt processing routine no.: 102
When the program is executed, operation will be as follows:
1-5-6 High-speed Counter 0 Overflows/Underflows
If the allowable counting range for high-speed counter 0 is exceeded, and
underflow or overflow status will occur and the counter’s PV will remain at
0FFF FFFF for overflows and FFFF FFFF for underflows until the overflow/
underflow status is cleared by resetting the counter. The allowable counting
ranges are as follows:
Up/Down Mode: F003 2767 to 0003 2767
Incrementing Mode: 0000 0000 to 0006 5535

Saves the comparison table in target matching format,
and begins comparing.
Begins continuous pulse output to IR10002 at 500 Hz.
When the high-speed counter value reaches 1000, subroutine
101 is called and the frequency of the pulse output is changed to
200 Hz.
When the high-speed counter value reaches 2000, subroutine 102
is called and the pulse output is stopped by setting the frequency
to 0.
