(1) Clock output mode register (CLOM)
(2) Selector 1
(3) Output control
(4) Selector 2
(5) ASTB/CLKOUT pin
480
Register that controls the operation of the clock output function.
Selector that selects the frequency of the clock to be output.
Controls the output signal in accordance with the contents of the clock output mode register (CLOM).
Selects either the ASTB signal or the CLKOUT signal as the signal to be output to the ASTB/CLKOUT pin.
Pin that outputs the signal selected by selector 2. While the RESET input is low, the ASTB/CLKOUT pin is in the
Hi-Z state, and when the RESET input becomes high it outputs a low-level signal, and then outputs a signal according
to the set function.
