1. These pins are used in an alternating fashion to compensate RTT by internal comparison to 3/4 VLDT and 1/4 VLDT and compensate RON by comparison to each other around 1/2 VLDT. For proper resistor value, see the AMD Athlon™ 64 Processor Motherboard Design Guide, order# 24665.
2. The unused L0_CTLIN_H/L[1] pins must be properly terminated such that the true pin is pulled High and the complement is pulled Low. Refer to the AMD Athlon™ 64 Processor Motherboard Design Guide, order# 24665, for details.
