The event fabric has two types of registers. The first type, a configuration register, is used to control and report the selection settings for a subscriber output. For each subscriber output, an address is mapped for a read register that contains a value representing the selection of the input event currently set for that subscriber output. For nonconfigurable outputs, only a read-only register is implemented. A read to that address returns the static, predefined value. The second type of register in the event fabric, of which there is only one, is an operational register named SWEV. This register sets and clears any of the four software events.
The AON event fabric is controlled through a series of registers residing in the MCU power domain. An AON-MCU interface block in the AON domain shadows these registers, thereby providing them for the AON block when the MCU is in power-down states.
