8.2 Introduction
TheMC68HC05P18AMCUcontainsasingle16-bitprogrammabletimer
with an input capture function and an output compare function. The 16-
bit timer is driven by the output of a fixed divide-by-four prescaler
operating from the PH2 clock. The 16-bit timer may be used for many
applications, including input waveform measurement while
simultaneously generating an output waveform. Pulse widths can vary
from microseconds to seconds depending on the oscillator frequency
selected. The 16-bit timer is also capable of generating periodic
interrupts. See
