The Charge Time Measurement Unit (CTMU) is a flex-
ible analog module that provides accurate differential
time measurement between pulse sources, as well as
asynchronous pulse generation. Its key features
include:
• Four edge input trigger sources
• Polarity control for each edge source
• Control of edge sequence
• Control of response to edges
• Precise time measurement resolution of 200 ps
• Accurate current source suitable for capacitive
• On-chip temperature measurement using a

Together with other on-chip analog modules, the CTMU
can be used to precisely measure time, measure
capacitance, measure relative changes in capacitance
or generate output pulses that are independent of the
system clock.
The CTMU module is ideal for interfacing with
capacitive-based sensors. The CTMU is controlled
through three registers: CTMUCON1, CTMUCON2
and CTMUICON. CTMUCON1 enables the module,
the edge delay generation, sequencing of edges, and
controls the current source and the output trigger.
CTMUCON2 controls the edge source selection, edge
source polarity selection and edge sampling mode. The
CTMUICON register controls the selection and trim of
the current source.
Figure 22-1
shows the CTMU block diagram.
