22.1.2
Figure 22.4 shows a typical method of connecting an external clock signal. To leave the XTAL pin
open, incidental capacitance should be 10 pF or less.
To input an inverted clock to the XTAL pin, the external clock should be set to high in standby
mode, subactive mode, subsleep mode, and watch mode. The frequency of the external clock
should be the same as that of the system clock (φ) when PFSEL is high. When PFSEL is low, an
external clock of 1/4 times the frequency of the system clock (φ) should be used.
When a specified clock signal is input to the EXTAL pin, internal clock signal output is
determined after the external clock output stabilization delay time (t
signal output is not determined during the t
in reset state. For the external clock output stabilization delay time, refer to table 25.5 and figure
25.8.
