Internal Clock Operation: Set the TPSC2–TPSC0 bits in TCR to select whether peripheral
module clock P or one of the four internal clocks created by dividing it is used (P /4, P /16,
P /64, P /256). Figure 11.4 shows the timing.
External Clock Operation: Set the TPSC2–TPSC0 bits in TCR to select the external clock
(TCLK) as the timer clock. Use the CKEG1 and CKEG0 bits in TCR to select the detection
edge. Rise, fall or both may be selected. The pulse width of the external clock must be at least
1.5 peripheral module clock cycles for single edges or 2.5 peripheral module clock cycles for
both edges. A shorter pulse width will result in inaccurate operation. Figure 11.5 shows the
timing for both-edge detection.
