The chip provides a programmable clock signal at the CLKOUT/RXD pin that is derived
from the internal system clock. To save power, this unit can be disabled by the SFR
CLKOUTEN bit. The Clock Generation Unit divides the internal clock by an adjustable
factor down to the desired CLKOUT frequency. The 20-bit wide division factor, stored in
the CLOCKOUT0, CLOCKOUT1 and CLOCKOUT2 registers, allows a CLKOUT-
frequency to be generated down to approximately 10 Hz. The 1:2 divider following the
20-bit counter creates the final CLKOUT signal with 50% duty cycle.
The resulting CLKOUT frequency can be calculated by:
