15.1.5.5 RXD/TXD Data Path Selection in Asynchronous Modes
Figure 15-8 shows the asynchronous mode data paths.

15.1.6
Synchronous mode supports half-duplex communication, basically for simple I/O expan-
sion via shift registers. Data is transmitted and received via pin RXD while pin TXD out-
puts the shift clock. These signals are alternate functions of port pins. Synchronous
mode is selected with S0CON_M=’000
8 data bits are transmitted or received synchronous to a shift clock generated by the in-
ternal baudrate generator. The shift clock is only active as long as data bits are transmit-
ted or received.
The lines RXDI and RXDO must be concatenated in the port logic to pin RXD.
