13.3 UART2 Baud Rate Timer Used by the First UART
In the Mode 1 and Mode 3 operation of the first UART, the user can select Timer 1 as the Baud Rate Generator
by clearing bits TCLK and RCLK in T2CON register. At this time, if URTS bit (in AUXR register) is set, then Timer
1 overflow signal will be replaced by the overflow signal of the UART2 Baud Rate Timer. In other words, the user
can adopt UART2 Baud Rate Timer as the Baud Rate Generator for Mode 1 or Mode 3 of the first UART as long
as RCLK=0, TCLK=0 and URTS=1. In this condition, Timer 1 is free for other application. Of course, if UART2
(Mode 1 or Mode 3) is also operated at this time, these two UARTs will have the same baud rates.
