ARINC 429/575 A4 Parity
Does the ARINC 429/575 A4 Communications module support both auto parity calculation and host controlled parity override?
When the Parity Disable bit is set to 0, it causes ARINC bit 32 to be treated as an odd parity bit. The transmitter calculates the ARINC odd parity bit and transmits it as bit 32. The receiver will check the received ARINC word for odd parity and will flag an error if it is not. When set to disable (1), parity generation and checking will be disabled for both the transmitter and receiver, and the ARINC bit 32 will be treated as data passing it on unchanged.
