Use of the HALT Instruction to Reduce Power Consumption – KBA91167

Version: **


Question: Can the HALT instruction be used to reduce power consumption?



No, the HALT instruction cannot be used to reduce power consumption. The HALT instruction will just stop the CPU (M8C). The internal main oscillator (IMO) and internal low-speed oscillator (ILO) would still be running, so the HALT instruction would not reduce current consumption.
