TXBYTEPRTY:

The transmit byte parity, TXBYTEPRTY, bit selects between byte parity and

word parity mode for inputs TXPRTY[1:0]. When the TXBYTEPRTY bit is set

to logic one, byte parity mode is selected; otherwise, word parity mode is

selected. In byte parity mode, TXPRTY[1] is the parity bit for inputs

TDAT[15:8], and TXPRTY[0] is the parity bit for inputs TDAT[7:0]. In word

parity mode, TXPRTY[1] is the parity bit for inputs TDAT[15:0], and

TXPRTY[0] is unused. Word parity mode can only be selected when the

BUS8 input is low (i.e., the 16-bit FIFO interface is selected).
