BC-Link Interface
The BC-Link is a proprietary bus developed to allow communication between a host controller device
to a companion device. This device uses this serial bus to read and write registers and for interrupt
processing. The interface uses a data port concept, where the base interface has an address register,
data register and a control register, defined in the SMSC’s 8051’s SFR space.
Refer to documentation for the BC-Link compatible host controller for details on how to access the
CAP1128 via the BC-Link Interface.
