The purpose of the host interface is to connect to the external system microcontroller (MCU).
The gm5060’s host microcontroller interface has two modes of operation: 2-Wire compatible
mode, and a 6-wire (nibble wide) interface mode, which are selected by bootstrapping options.

4.18.1 2-wire Configuration
The 2-wire compatible connection consists of a serial clock (SCL) and bi-directional serial data
line (SDA). The bus master drives the SCL clock and either the master or slave may drive the
SDA line (open drain). The gm5060 operates as a slave on the interface and the external MCU as
the master. The SDA and SCL lines are shared with the 6-wire communication lines HFSn and
HCLK respectively, as illustrated below.
