“MOV @AL, AH”, “MOVW @AL, AH” Instructions
8.
When the above instruction is performed to I/O space, an unnecessary writing operation (#FF, #FFFF) may be
performed in the internal bus.
Use the compiler function for inserting an NOP instruction before the above instructions to avoid the writing
operation.
Accessing RAM space with the above instruction does not cause any problem.
Initialization
9.
In the device, there are internal registers which is initialized only by a power-on reset. To initialize these registers,
turning on the power again.
10. Caution on operations during PLL clock mode
If the PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even
when there is no external oscillator or external clock input is stopped. Performance of this operation, however,
cannot be guaranteed.
