Notes:
1. Not implemented on MPC7447
2. Caution: The input threshold selection must agree with the OVDD/GVDD voltages supplied. See notes in Table 2.
3. If used, pull-down resistors should be less than 250
.
4. Applicable to L3 bus interface only. HRESET is the inverse of HRESET.

Notes:
1. These are the recommended and tested operating conditions. Proper device operation outside of these conditions
is not guaranteed.
2. This voltage is the input to the filter discussed in Section 1.9.2, “PLL Power Supply Filtering,” and not necessarily
the voltage at the AVDD pin, which may be reduced from VDD by the filter.
3. HRESET is the inverse of HRESET.
