4.3.2 Event Fabric Overview

There are two main event fabric blocks in the CC26xx and CC13xx family. One in the MCU power domain

(MCU event fabric) and the other in the AON power domain (AON event fabric).

simplified overview of the two modules together. The MCU event fabric is one of the subscribers to the

AON event fabric.

MCU Event Fabric

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

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.

AON Event Fabric

The AON event fabric resides in the AON power domain where the wake-up controller, the debug

subsystem, the AUX domain, and the real-time clock (RTC) reside.
