Configure serial port interrupts

Hi. I’m having some trouble figuring out exactly how to configure serial port interrupts on a 9210.

For example, say I want to enable an interrupt using character match0, I assume this is done by writing a ‘1’ into the MATCH0 bit of the the Serial Interrupt Enable register for UART A with narm_write_reg, and also writing the specific character into the Receive Character Match Control register for UART A, also with narm_write_reg?

I’m having a tough time figuring out what the actual names/macros are for the registers I need to write to.

actually, the drivers themselves consume the interrupts. You will need to implement some code that fires a software interrupt as the data comes in through the ports if that’s what you really need.
