This section is a summary of the host bus interface modes available on the S1D13705 that
would be used to interface to the VR4102/VR4111.
The S1D13705 implements a 16-bit interface to the host microprocessor which may operate
in one of several modes compatible with most of the popular embedded microprocessor
families. The interface mode used for the VR4102/VR4111 is:
• Generic #2 (External Chip Select, shared Read/Write Enable for high byte, individual
