FAST_SEL0
RW
R
0
Select signal for fast clock output #0
NC
0
Disabled - output is 0. For power savings, clocks are
blocked before entering any muxes, including
PATH_SEL0 and HFCLK_SEL0.
ECO
1
External Crystal Oscillator (ECO)
EXTCLK
2
External clock input (EXTCLK)
ALTHF
3
Alternate High-Frequency (ALTHF) clock input to
SRSS
TIMERCLK
4
Timer clock. It is grouped with the fast clocks because
it may be a gated version of a fast clock, and therefore
may have a short high pulse.
PATH_SEL0
5
Selects the clock path chosen by PATH_SEL0 field
HFCLK_SEL0
6
Selects the output of the HFCLK_SEL0 mux
SLOW_SEL0
7
Selects the output of
CLK_OUTPUT_SLOW.SLOW_SEL0
