Flags (FLAG)
There are two types of flags: carry flag (CF) and status flag (SF).
These are set and cleared according to conditions specified by instructions.
The status flag is initialized to 1 at reset.
2.10 Clock generator, Timing generator
Figure 2.6 shows the clock generator and timing generator configuration.

2.10.1
Clock generator
The clock generator is a circuit which generates the fundamental clock pulse (CP) as the basis for
the system clock supplied to the CPU. The fundamental clock is easily established by connecting
the oscillator to the XT and XT pins. A clock can also be input from an external oscillator.
Clock input to the XT pin is used as the fundamental clock.
The clock generator stops oscillation during hold mode.

2.10.2
Timing generator
The timing generator is a circuit which uses the fundamental clock to generate various system
clocks for the CPU and peripheral hardware.
