MOTOROLA
Timeout Tolerance
The timing system is based on a free-running 16-bit counter with a four-stage programmable prescaler.
A timer overflow function allows software to extend the timing capability of the system beyond the 16-
bit range of the counter.
The timer has three channels for input capture, four channels for output compare, and one channel that
can be configured as a fourth input capture or a fifth output compare. In addition, the timing system in-
cludes pulse accumulator and real-time interrupt (RTI) functions, as well as a clock monitor function,
which can be used to detect clock failures that are not detected by the COP.
Refer to 11 Pulse Accumulator and 10.1 Real-Time Interrupt for further information about these func-
tions. Refer to the following table for a summary of the crystal-related frequencies and periods.
