Rx-FIFO write and read offset address.
APB_RX_RADDR | This register stores the offset address in RX-FIFO when software reads data from Rx-FIFO via APB. UART0 is 10’h100. UART1 is 10’h180. |
RX_WADDR | This register stores the offset address in Rx-FIFO when Rx-FIFO_Ctrl writes Rx-FIFO. UART0 is 10’h100. UART1 is 10’h180. |
