8. 24-bit Timer Counter
The 24-bit timer counter consists of a 24-bit up-counter, an 8-bit output buffer register, and a control register.
The count value output by this timer counter is used to generate the base time used for input capture and output
compare.
The interrupt functions provided are timer overflow interrupts and timer intermediate bit interrupts.
The
intermediate bit interrupt permits four time settings.
The 24-bit timer counter value is cleared to all zeroes by a reset.
