Active-halt and Halt modes
Active-Halt and Halt modes are the two lowest power consumption modes of the MCU. They
are both entered by executing the ‘HALT’ instruction. The decision to enter either in Active-
Halt or Halt mode is given by the LTCSR/ATCSR register status as shown in the following
table:
