Attaching HSC interrupt routines in your program
All high-speed counter modes support an interrupt event when the current value of the HSC
is equal to the loaded preset value. Counter modes that use an external reset input support
an interrupt on activation of the external reset. All counter modes except modes 0 and 1
support an interrupt on a change in counting direction. Each of these interrupt conditions can
be enabled or disabled separately. For a complete discussion on the use of interrupts, see
the section about Interrupt instructions (Page 322).
