#### 16550 CODE ####
The 16550 Code in this repository was developed for the ATMega 2560, which is
the Atmel AVR on the Arduino Megas from Revision 3 onwards.
The following port Registers have been used for the following things on the AVR:
- PORTF
This Port-Register is used for the Data-Bus. It is in most usecases
onedirectional, but if needed, for example for a feedback read, it can
be used as bi-directonal
- PORTE[0;2]
This part of the Port-Register is used for the Address bus and is
always driven by the AVR.
- PORTE[3]
This pin is used for the !WR pin of the 16550 UART and is always driven
by the AVR. THE !WR pin is used to signal a write access.
- PORTE[4]
This pin is used for the !RD pin of the 16550 UART and is always driven
by the AVR. The !RF pin is used to signal a read access.
- PORTE[5]
This pin is used for the MR pin of the 16550 UART and is always
driven by the AVR. The MR pin is used to reset the IC.
- PORTE[6]
This pin is used for the !CS3 pin of the 16550 UART and is always
driven by the AVR. The !CS3 pin is used to tell the cheip when data
on the data and address bus is meant for it.
