This section identifies the requirements for initializing the surrounding modules when the HDQ1W module is to be used for the first time after a device reset. This initialization of surrounding modules is based on the integration and environment of the HDQ1W. Refer to the HDQ1W Module Integration and Environment Sections for further information.
| Surrounding Modules | Comments |
|---|---|
| PRCM | Module interface and functional clocks must be enabled. The interface clock must not be slower than the functional clock (HDQ1W_ICLK ≥ HDQ1W_FCLK). For more information about the module configuration, see Power, Reset, and Clock Management. |
| Control Module | Module specific pad muxing and pullup must be set in the control module. If an external pullup is used, the internal pullup/pulldown must be disabled. For more information about the module configuration, see Control Module. |
| IRQ_CROSSBAR/INTC | Interrupt crossbar and interrupt controller configuration must be done to enable the interrupts from HDQ1W module. See Interrupt Controllers, and IRQ_CROSSBAR Module Functional Description. |
