Bit 24 — CardBus Capable
A ‘1’ in this bit indicates that the CL-PD6833 is capable of supporting PC Card 32 (CardBus) cards.
Bit 25 — LOCK# Support
A ‘1’ indicates that the CL-PD6833 is capable of supporting operations involving the LOCK#
signal.
Note that bit 25 of the Device Implementation Byte D register must be referenced to determine
whether LOCK# is a supported signal in the system implementation.
Bit 26 — CLKRUN# Support
A ‘1’ indicates that the CL-PD6833 is capable of supporting PCI Mobile Specification CLKRUN#
signalling for control of system clock turn on/turn off.
Note that the least-significant bit of the Device Implementation Byte D register must be referenced
to determine whether this feature is supported in the system implementation.
Bits 30:27 — RFU (reserved for future use)
Bit 31 — Extended Definitions
A ‘0’ indicates that there is no extended definition.
