Figure 24-35 is the HDQ1W block diagram.
The HDQ_CTRL_STATUS[0] MODE bit allows selection between the HDQ and 1-Wire protocols. This bit is assumed static for design purposes. The configuration is in HDQ mode by default.
Figure 24-36 shows the protocol-dedicated register scheme.
The receive and transmit operations of the HDQ1W module are performed with respect to the timing of the slower HDQ protocol. When the 1-Wire protocol is used, it runs at lower speed than its full capabilities, but is still able to meet the timing requirements and practical considerations.
