Preliminary

• Enter a 16-bit initial value in timer registers TH2/TL2. It can be the same as the reload value or different
depending on the application.
• To start the timer, set TR2 run control bit in T2CON register.
It is possible to use timer 2 as a baud rate generator and a clock generator simultaneously. For this configuration,
the baud rates and clock frequencies are not independent since both functions use the values in the RCAP2H and
RCAP2L registers.
