and then I would like to do something like this (i know this isn't right)
unsigned int vector_table = (unsigned int *)RAM_VECTOR_LOCATION;
vector_table[UART4_RX_TX_IRQn] = (unsigned int)UART4_IRQHandler;
Essentially I would like to index into my vector table to install new handlers but I don't know what the syntax is. This seems like a hazy question but I can't figure out how to articulate it.
