hello, i am using usart of Atmega32. and i have this question: according to the datasheet, the highest baud rate is 1M. this 1M means 1000000 or 1024*1024? and the error is said to be 0%. is it real? on the PC side, i use a RS232 to usb cable, whose highest speed is also said to be 1M. does it mean my device can work at 1Mbps stably?
