2. External Clock Operation: Set the TPSC2 to TPSC0 bits in TCR to select the external clock
3. On-Chip RTC Clock Operation: Set the TPSC2 to TPSC0 bits in TCR to select the on-chip
(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 accurate operation. Figure 12.5 shows the
timing for both-edge detection.
