Functional Description and Application Information
4.18
4.18.1
4.18.1.1
The basic timer consists of a 16-bit, software-programmable counter driven by a seven-stage programmable prescaler.
This timer can be used for many purposes, including input waveform measurements while simultaneously generating an output
waveform. Pulse widths can vary from microseconds to many seconds.
This timer contains 4 complete input capture/output compare channels [IOC 3:2]. The input capture function is used to detect a
selected transition edge and record the time. The output compare function is used for generating output signals or for timer
software delays.
A full access for the counter registers or the input capture/output compare registers should take place in 16bit word access.
Accessing high byte and low byte separately for all of these registers may not yield the same result as accessing them in one
word.
4.18.1.2
The TIM16B4C includes these distinctive features:
4.18.1.3
The TIM16B4C is only active during Normal mode.
4.18.1.4
