TPU3 ROM Functions
D.5
Frequency Measurement (FQM)
FQM counts the number of TPU-channel input pulses during a user-defined window period. The function
has single-shot and continuous modes. In continuous mode, no pulses are lost between sample windows,
and the user can select whether to detect pulses on the rising or falling edge. This function is intended for
high-speed measurement. (Measurement of slow pulses with noise rejection can be made with PTA.) See
Freescale TPU Progamming Note Frequent Measurement TPU Function (FQM),
(TPUPN03/D).
Figure D-6
shows all of the host interface areas for the FQM function.
