The Charge Time Measurement Unit (CTMU) is a
flexible
differential time measurement between pulse sources,
as well as asynchronous pulse generation. By working
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 with a specific time delay. The CTMU is
ideal for interfacing with capacitive-based sensors.
The module includes the following key features:
• Up to 28
• On-chip precision current source
• Four-edge input trigger sources
• Polarity control for each edge source
• Control of edge sequence
• Control of response to edges

• Time measurement resolution of 1 nanosecond
• High precision time measurement
• Time delay of external or internal signal
• Accurate current source suitable for capacitive
The CTMU works in conjunction with the A/D Converter
to provide up to 28
measurement, depending on the specific device and
the number of A/D channels available. When config-
ured for time delay, the CTMU is connected to the
C12IN1- input of Comparator 2. The level-sensitive
input edge sources can be selected from four sources:
two external input pins (CTED1/CTED2) or the ECCP1/
(E)CCP2 Special Event Triggers.
