Table 15. Clock 1 Prescale Select (Continued)
The Stop condition provides a Timer Enable/Disable function. The CK down divided modes
are scaled directly from the 12 MHz system clock. If the external pin modes are used for
Timer/Counter1, transitions on PB1/(T1) will clock the counter even if the pin is configured as
an output. This feature can give the user SW control of the counting.
