CCS/PROCESSOR-SDK-AM437X: Serial port interrupt configuration

Hi zhuangbin,

PRSDK serial port LLDs are described in the Developer's Guide, the latest version of which is available here: http://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_01_00_08/rtos/index.html.

The UART LLD, for example, is documented here: http://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_01_00_08/rtos/index_device_drv.html#uart.

UART LLD examples for non-DMA (CPU interrupt) & DMA mode are described here: http://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_01_00_08/rtos/index_device_drv.html#examples

Additional documentation for the UART LLD API can be located in pdk_am437x_1_0_16\packages\ti\drv\uart\docs\doxygen\html\index.html.

It shouldn't be necessary (and it isn't possible) to configure serial port IP interrupts for PRSDK LLDs in XGCONF. Interrupt configuration should be handled internally by the LLD. The hardware configuration for a particular IP instance can be located in the LLD SoC file, e.g. for AM437x UART this is located in pdk_am437x_1_0_16\packages\ti\drv\uart\soc\am437x\UART_soc.c.

If needed, the SOC level configuration can be read & modified by the application using the XXX_socGetInitCfg()/XXX_socSetInitCfg() API functions. Usage of these functions is shown in the serial port examples. 

Regards,
Frank
