Description
Even Parity Select.
Use odd parity for transmit and receive. The total number of 1 bits in the transmit
data plus parity bit is odd. Used as SPACE bit in Multidrop Mode. See
page 189 for parity select definitions. Note: Receive Parity is set to SPACE in
multidrop mode.
Use even parity for transmit and receive. The total number of 1 bits in the transmit
data plus parity bit is even. Used as MARK bit in Multidrop Mode. See
page 189 for parity select definitions.
Parity bit transmit and receive is disabled.
Parity bit transmit and receive is enabled. For transmit, a parity bit is generated and
transmitted with every data character. For receive, the parity is checked for every
incoming data character. In Multidrop Mode, receive parity is checked for space
parity.
