• Peripheral event transferred to another peripheral to directly trigger an action in hardware (Generic Event)

– Example: TIMx timer peripheral publishes a periodic event to the ADC subscriber port, and the ADC uses

the event to trigger start-of-sampling

Refer to the Event chapter of the MSPM33C3x 160-MHz Microcontrollers Technical Reference Manual.

Table 8-7. Generic Event Channels

A generic route is either a point-to-point (1:1) route or a point-to-two (1:2) splitter route in which the peripheral publishing the

event is configured to use one of several available generic route channels to publish its event to another entity (or entities, in

the case of a splitter route), where an entity may be another peripheral, a generic DMA trigger event, or a generic CPU event.

8.9 Error Aggregator Module (EAM)

The Error Aggregator Module (EAM) aggregates errors that include but are not limited to single error correction

(SEC) and double error detection (DED) for the system memory and security errors. EAM latches the error into

corresponding register that is forwarded to SYSCTL to generate an NMI or interrupt the CPU based on the

priority of the error. The EAM module can be protected by a security firewall based on the GSC setting to allow

customer critical code in secure mode of the application to handle the error in a context safe method.

The EAM supports the following features:

• ECC error logging for SEC and DED from flash and SRAM

• Security error logging for non-secure access to a firewall region for memory and peripherals

• Security error logging for hide protected region in the flash

• First error logged with initiator and type of access error logged

8.10 GPIO

The general purpose input/output (GPIO) peripheral provides the user with a means to write data out and read

data in to and from the device pins. Through the use of the Port A, Port B and Port C GPIO peripherals, these

devices support up to 93 GPIO pins.

The key features of the GPIO module include:

• Set/Clear/Toggle multiple bits without the need of a read-modify-write construct in software

• "FastWake" feature enables low-power wakeup from STOP and STANDBY modes for any GPIO port

• User controlled input filtering

For more details, see the GPIO chapter of the MSPM33C3x 160-MHz Microcontrollers Technical Reference

Manual.
