PIN 6 - MR
When MR is a 1, the control word is set to 0X10 0101 (CR7 -
CR0).
For the receiver this sets up 8 bit mode with the
receiver and parity enabled. MR also initializes the registers
and logic. The first ARINC reception will only occur

PIN12 - RXC
This pin must have a clock applied that is 4X the desired

PIN13 - FCR
In 8 bit mode, this pin flags the first character (byte) received.
In 32 bit mode, this pin goes high for a valid 32 bit word. The
