27 SMT - Signal Measurement Timer

The Signal Measurement Timer (SMT) is a 24-bit counter with advanced clock and gating logic, which can be configured for measuring a variety of digital signal parameters such as pulse width, frequency and duty cycle, and the time difference between edges on two signals.

Features of the SMT include:
  • 24-Bit Timer/Counter
  • Two 24-Bit Measurement Capture Registers
  • One 24-Bit Period Match Register
  • Multi-Mode Operation, Including Relative Timing Measurement
  • Interrupt-on-Period Match and Acquisition Complete
  • Multiple Clock, Signal and Window Sources
