Notes:
1. Caution: The input threshold selection must agree with the OVDD/GVDD voltages supplied. See notes in Table 2.
2. To select the 2.5-V threshold option for the processor bus, BVSEL should be tied to HRESET so that the two
signals change state together. Similarly, to select 2.5 V for the L3 bus, tie L3VSEL to HRESET. This is the
preferred method for selecting this mode of operation.
3. Applicable to L3 bus interface only. HRESET is the inverse of HRESET.
4. If used, pulldown resistors should be less than 250
