PORT FUNCTION
DEFINITION OF CLOCK AND CYCLE
Operation source clock
The operation source clock is the source clock to operate this
product. In this product, the following clocks are used.
Clock (f(XIN)) by the external ceramic resonator
Clock (f(XIN)) by the external input
System clock
The system clock is the basic clock for controlling this product.
The system clock is selected by the register MR.
Instruction clock
The instruction clock is a signal derived by dividing the system
clock by 3. The one instruction clock cycle generates the one
machine cycle.
Machine cycle
The machine cycle is the standard cycle required to execute the
instruction.
Note 1.The frequency divided by 8 is selected after system is
released from reset.
