The descriptions of the RXDTP and TXCKP bits
(BAUDCON<5:4>) are being revised as shown
below (changes in bold).
RXDTP: Data/Receive Polarity Select bit (Asynchronous mode only)
Asynchronous mode:
1 = Receive data (RX) is inverted (active-low)
0 = Receive data (RX) is not inverted (active-high)
TXCKP: Clock and Data Polarity Select bit
Asynchronous mode:
1 = Idle state for transmit (TX) is a low level
0 = Idle state for transmit (TX) is a high level
Synchronous mode:
1 = Idle state for clock (CK) is a high level
0 = Idle state for clock (CK) is a low level
