SECTION 8
TIMER
The timer consists of a 16-bit, software-programmable counter driven by a xed
divide-by-four prescaler. This timer can be used for many purposes, including
input waveform measurements while simultaneously generating an output
waveform. Pulse widths can vary from several microseconds to many seconds.
Refer to Figure 8-1 for a timer block diagram.
Each specic 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 specic timer function allows full control of
that function; however, an access of the high byte inhibits that specic timer
function until the low byte also is accessed.
NOTE
The I bit in the CCR should be set while manipulating both the high
and low byte register of a specic timer function to ensure that an
interrupt does not occur.
