12.2.4 Baud Rate Generator Mode
Baud rate generator mode is enabled by setting either RCLK or TCLK in T2CON. In baud rate
generator mode, Timer/Counter 2 is a 16-bit counter with auto-reload when the count rolls over from
FFFFh. However, rolling-over does not set TF2. If EXEN2 is set, then a negative transition on the
T2EX pin sets EXF2 bit in the T2CON register and causes an interrupt request.
RCLK+TCLK=1, CP/RL2 =0
