Timer Module (TIM16B8CV2) Block Description
22.1
The basic timer consists of a 16-bit, software-programmable counter driven by a enhanced 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 8 complete input capture/output compare channels and one pulse accumulator. 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. The 16-bit pulse accumulator
is used to operate as a simple event counter or a gated time accumulator. The pulse accumulator shares
timer channel 7 when in event mode.

MC9S12XE-Family Reference Manual Rev. 1.23
Table 22-1. Revision History
- Revised flag clearing procedure, whereby TEN or PAEN bit must be set
when clearing flags.
- Add fomula to describe prescaler
- Correct typo: TSCR ->TSCR1
- Correct reference: Figure 1-25 -> Figure 1-31
- Add description, “a counter overflow when TTOV[7] is set”, to be the
condition of channel 7 override event.
- Phrase the description of OC7M to make it more explicit
- Add
- in TCRE bit description part,add Note
- Add
