Data transfer in USART through FIFO

[richa.verma]

In USART, can CPU or DMA directly read or write data in FIFO? Or do i need to use separate register such that this register stores the data coming from CPU and then write this data from register to FIFO. like wise store data from FIFO to register and then send this data to CPU? Help me out!!

you can directly read and write data no need to use separate register but you have to check the status registers of transmission and reception in order to avoid data losses
