D.5 Frequency Measurement (FQM)
MPC555 / MPC556
USER’S MANUAL
FQM counts the number of input pulses to a TPU channel during a user-defined win-
dow period. The function has single shot and continuous modes. No pulses are lost
between sample windows in continuous mode. The user selects whether to detect
pulses on the rising or falling edge. This function is intended for high speed measure-
ment; measurement of slow pulses with noise rejection can be made with PTA.See
Motorola TPU Progamming Note
(TPUPN03/D).
Figure D-6
shows all of the host interface areas for the FQM function.
