Product data sheet
6.9 Timer 2
Timer 2 is a 16-bit Timer/Counter which can operate as either an event timer or an event
counter, as selected by C/T2 in the special function register T2CON. Timer 2 has four
operating modes: Capture, Auto-reload (up or down counting), Clock-out, and Baud Rate
Generator which are selected according to
Table

Description
Timer 2 overflow flag set by a Timer 2 overflow and must be cleared by
software. TF2 will not be set when either RCLK or TCLK = 1 or when
Timer 2 is in Clock-out mode.
Timer 2 external flag is set when Timer 2 is in capture, reload or baud
rate mode, EXEN2 = 1 and a negative transition on T2EX occurs. If
Timer 2 interrupt is enabled EXF2 = 1 causes the CPU to vector to the
Timer 2 interrupt routine. EXF2 must be cleared by software.
Receive clock flag. When set, causes the UART to use Timer 2
overflow pulses for its receive clock in modes 1 and 3. RCLK = 0
causes Timer 1 overflow to be used for the receive clock.
