SECTION 11
TIMER 1
11.1 Introduction
This timer can be used for many purposes, including input waveform
measurements while simultaneously generating an output compare interrupt.
Pulse widths can vary from several microseconds to many seconds. Refer to
Figure 11-1.
Because the timer has a 16-bit architecture, each specific functional segment
(capability) is represented by two registers. These registers contain the high and
low byte of that functional segment. Generally, accessing the low byte of a specific
timer function allows full control of that function; however, an access of the high
byte inhibits that specific timer function until the low byte is also accessed.
NOTE
The I bit in the CCR should be set while manipulating both the high
and low byte register of a specific timer function to ensure that an
interrupt does not occur.
