1. TCLK is a test clock driven in on the XTALIN input in test mode.
2. “Normal” mode of operation
3. Range of reference frequency allowed is min. = 14.316, nom. = 14.31818 MHz, max. = 14.32 MHz.
4. Frequency accuracy of 48 MHz must be +167PPM to match USB default.
5. Mid. is defined a Voltage level between 1.0V and 1.8V for three-level input functionality. Low is below 0.8V. High is above 2.0V.
6. Required for DC output impedance verification.
7. These modes are to use the SAME internal dividers as the CPU = 200 MHz mode. The only change is to slow down the internal VCO to allow under clock
