Bits TCLK and/or RCLK in register T2CON allow the serial port transmit and receive baud
rates to be derived from either timer 1 or timer 2. When TCLK = 0, timer 1 is used as the
serial port transmit baud rate generator. When TCLK = 1, timer 2 is used. RCLK has the
same effect for the serial port receive baud rate. With these two bits, the serial port can
have different receive and transmit baud rates, one generated by timer 1, the other by
timer 2.
The baud rate generation mode is like the auto-reload mode, in that a rollover in TH2
causes the timer 2 registers to be reloaded with the 16-bit value in registers RCAP2H and
RCAP2L, which are preset by software.
