Sub clock oscillation circuit generates the sub clock. The sub clock becomes a clock source for the CPU
clock and a count source for the timers A and B. The same frequency, fc, as the sub clock can be output from
the CLK
The sub clock oscillation circuit is configured by connecting a crystal oscillator between the X
X
oscillation circuit in stop mode to reduce power consumption. The externally generated clock can be
applied to the X
vary with each oscillator. Use the circuit constant recommended by each oscillation manufacturer.
The sub clock stops after reset. The feedback resistor is separated from the oscillation circuit. When the
PD8_6 and PD8_7 bits in the PD8 register are set to "0" (input mode) and the PU25 bit in the PUR2
register is set to "0" (no pull-up), set the CM04 bit in the CM0 register to "1" (X
function). The sub clock oscillation circuit starts oscillating. To apply the external clock to the X
the CM04 bit to "1" when the PD8_6 bit is set to "0" and the PU25 bit to "0". The clock applied to the X
pin becomes the clock source for the sub clock.
When the CM07 bit in the CM0 register is set to "1" (sub clock) after the sub clock oscillation has stabi-
lized, the sub clock becomes the CPU clock.
All clocks, including the sub clock, stop in stop mode. Refer to 8.5 Power Consumption Control for
details.
