19.13 I/O Pin Control
The UART module shares pins with port input/output
control and, in some cases, with other modules. To
configure a pin for use by the UART, any modules shar-
ing the pin must be disabled. After configuring the
UART, the corresponding I/O pins must be configured
using the TRIS bit to be an input or output as is required
by the UART.
