A care apparatus is described that has the capability to sense environmental characteristics, detect a dependent’s condition, and carry out suitable actions to care for the dependent. The neutron generator generates neutrons and the shield reduces external radiation exposure. The input is coupled to a reference voltage. If a CPU in the microcomputer accesses set data for the dedicated register at the head address of the external memory and receives the set data including the wait information of data to be transferred when reset is released, the data is transferred to the internal RAM via an address bus and a data bus by executing the transfer program in the internal ROM.
