6. CONFIGURATION REGISTER
6.1
W83L518D/W83L519D implement compatible PNP protocol to access configuration registers for
setting up different types of configurations. There are four Logical Devices (Logical Device 0 to
Logical Device 3) in W83L518D/W83L519D which correspond to four major functions: Smart Card
Interface (logical device 0), Memory Stick Interface (logical device 1), GPIO (logical device 2) and SD
Memory Interface (logical device 3). Each Logical Device has its own configuration registers (CR30
and above). Host can access those registers by writing an appropriate logical device number into
logical device select register at CR07 first.
