Will like some help on how to disable and enable the 4 UARTs on the MEGA.
For the Uno I see the following code for the single UART it has:
UCSR0B &= ~(_BV(TXEN0)); //disable UART TX UCSR0B &= ~(_BV(RXEN0)); //disable UART RX
I would like to know to do the same for the 4 UARTs on the Mega.
Thanks in advance.
