CAP1126
4.8 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
8051’s SFR space.
Refer to documentation for the BC-Link compatible host controller for details on how to access the CAP1126 via the BC-
Link Interface.
