3 Parameter Measurement Information
This section contains the timing waveforms and parameter values for MCLKOUT and several
microcontroller interface configurations possible when using the TCM4300. The timing parameters are
contained in Section 3.1 through Section 3.11. The timing waveforms are shown in Figures 3–1 through
3–11. All parameters shown in the separate waveforms have their values listed in an associated table. Not
all parameter values listed in the tables are necessarily shown in an associated waveform.
