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. |
