Error in UART Core with Avalon® Interface Chapter

The UART chapter of the Peripherals Handbook incorrectly states:

"When parity is Even, the parity bit is 1 if the character has an even number of 1 bits; otherwise, the parity bit is 0. Similarly, when parity is Odd, the parity bit is 1 if the character has an odd number of 1 bits."

This paragraph should read:

"When parity is Even, the parity bit is 1 if the number of 1's in the character plus the parity bit is even; otherwise, the parity bit is 0. Or, in other words, the Parity bit is set to '0' when there is an even number of '1' bits in the character. Similarly, when parity is Odd, the parity bit is 1 if the number of 1's in the character plus the parity bit has an odd number of 1 bits. Or, in other words, the Parity bit is set to '0' when there is an odd number of '1' bits in the character."
