To allow the system to determine baud rates of
received characters, the input can be optionally linked
to a selected capture input. To enable this mode, the
user must program the input capture module to detect
the falling and rising edges of the Start bit.
For most device variants, the IC1 capture channel is
used to detect the baud rate for UART1. The IC2
capture channel is used for UART2. Refer to the
specific device data sheet for details.
18.10 UART Operation During CPU
18.10.1
When the device enters Sleep mode, all clock sources
to the module are shutdown and stay at logic ‘0’. If
entry into Sleep mode occurs while a transmission is
in progress, then the transmission is aborted. The
UxTX pin is driven to logic ‘1’. Similarly, if entry into
Sleep mode occurs while a reception is in progress,
then the reception is aborted. The UxSTA, UxMODE,
transmit and receive registers and buffers, and the
UxBRG register are not affected by Sleep mode.
If the Wake bit (UxSTA<7>) is set before the device
enters Sleep mode, then a falling edge on the UxRX
pin will generate a receive interrupt. The Receive
Interrupt Select mode bit (URXISEL) has no effect for
this function. If the receive interrupt is enabled, then
this will wake-up the device from Sleep. The UARTEN
bit must be set in order to generate a wake-up
interrupt.

SLEEP MODE
Preliminary
18.10.2
For the UART, the USIDL bit selects if the module will
stop operation when the device enters Idle mode, or
whether the module will continue on Idle. If USIDL = 0,
the module will continue operation during Idle mode. If
USIDL = 1, the module will stop on Idle.
