1.	Which pins are used for additional DMA control?(a) RXRDY(b) RD(c) MR(d) INRI have been asked this question in homework.The origin of the question is UART-2 topic in portion Basic Peripherals of Embedded Systems
Answer» The correct choice is (a) RXRDY To explain I would say: TheRXRDY and TXRDY are TWO active low pins which are used for ADDITIONAL DMA CONTROL. It can be used for DMA transfers to and from the read and WRITE buffers.
