UART0/SPI1
Note:
This interface is not supported on the HL6528RDx and HL75xx.
The UART0/SPI1 connector,
the HL Series embedded module's debug port interface.
This interface is used for legacy HL6528x "SpyTracer" debugging. For more information about
SpyTracer debugging, refer to section 5.1 Getting SpyTracer Debugging Data.
When using the HL85xxx, the operating mode of this connector can be set using SW603. When using
a legacy HL6528x module, the UART0 connector functions as an SPI to UART interface regardless of
SW603's setting.
