B2_B3
R/O
B2_B3 Support for D3HOT: When BPCCE is read as 1, this bit is driven
as a logic level 1 to indicate that the secondary bus clock outputs will be
stopped and driven LOW when the device is placed in D3HOT. This bit is
undefined when BPCCE is read as 0.

Bus Power/Clock
Control Enable
R/O
Bus Power / Clock Control Enable: When the BPCCE pin is tied
HIGH, this bit is read as a 1 to indicate that the bus power/clock control
mechanism is enabled. When the BPCCE pin is tied LOW, this bit is
read as a 0 to indicate that the bus power / clock control mechanism is
disabled.
