1. Software using MOVE instruction using internal CPU registers and peripheral registers
Hints for low power operation:
1. Use the low power RAM instead of the RAM for all parameters that are accessed frequently. The average
2. Rather than using the circuit at low speed, it is better to use the circuit at higher speed and switch off the blocks
3. The power consumption of the program memory is an important part of the overall power consumption. In case

current consumption for the low power RAM is about 40 times lower than for the RAM.

you intend to use a ROM version and power consumption is too high, please ask us to provide you with a
circuit version with smaller ROM size.
