UART Address Matching on K66

[jeremyanderson]

I can see from this:

#define FSL_FEATURE_UART_HAS_ADDRESS_MATCHING (1)

that there may be an address matching capability in the UART, but I don't see any documentation of its use in the API.  Can someone point me to a more detailed set of documentation for the UART used in this SOC?  Even better, any experience on here with enabling and using this feature?

HI Jeremy.

FSL_FEATURE_UART_HAS_ADDRESS_MATCHING is used in KSDK1.x SW package.

Normally it is defined in <mcu_name>_features.h file and used in fsl_uart_hal.c file.

it is to brief Supports two match addresses to filter incoming frames.

I just checked there is no document describing this MACRO.

KSDK1.3  API reference manual can be downloaded here:

Have a great day,
