Parity control
Parity control
Transmission gap
Reset FIFO
Number of msg
The transmission frequency can be computed by dividing the CLK ARINC frequency by
the frequency register value.
The frequency register must be loaded with a value greater or equal to 2.
•
The transmitter control register is accessible for reading and writing operations.
The Transmitter Control Register
“transmission gap” which is the delay between two 32-bit ARINC messages (in
Comments
- 0: channel out of service (stops on going transmission)
- 1: channel in service
- 1 to 0: transition is not allowed at the same time as an 1 to 0 transition of the bit 4
- when the transmitter FIFO is empty and when no transmission is on going, the first
write access to the FIFO has to be preceded by the following sequence: reset to 0
and then set to 1
0: normal operating
1: test, output are only driven on internal lines for input testing
0: even parity calculation
1: odd parity calculation
0: parity disable, Bit 32 of the message stays unchanged
1: parity enable. Bit 32 of the message will be forced by parity control
ARINC bit)
- write a 0 in this bit reset the FIFO counter
- this bit must be set to 1 before any write in the transmit buffer.
- 1 to 0: transition is not allowed at the same time as an 1 to 0 transition of the bit 15
these four bits indicate the available space within the FIFO
