The 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
