The clocks GCLK1_50 and GCLK2_50 frequency is:

CLKOUT has the same frequency as the general system clock (GCLK2_50). Unlike the main system clock
GCLK1/GCLK2 however, CLKOUT (and GCLK2_50) represents the external bus clock, and thus will be
one-half of the main system clock if the external bus is running at half speed (EBDF = 0b01). The
CLKOUT frequency (system frequency) defaults to VCO/2. CLKOUT can drive full, half, or quarter
strength; it can also be disabled. The drive strength is controlled in the system clock and reset-control
register (SCCR) by the COM[0:1] and CQDS bits. (See
(SCCR)”). Disabling or decreasing the strength of CLKOUT can reduce power consumption, noise, and
electromagnetic interference on the printed circuit board.
When the PLL is acquiring lock, the CLKOUT signal is disabled and remains in the low state (provided
that BUCS = 0).
