MICROCOMPUTER’S TERMINAL DESCRIPTION

How to Read the Destination Type

The destination type is set by reading the following microcomputer ports at

the time of reset-start of the microcomputer.

Once the destination type is read and set during the microcomputer

resetting, any change in the ports during the microcomputer operation will

be ignored.

CAUTION : For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to parts list).Indicates safety critical components. To reduce the risk of electric shock, leakage-current or resistance measurements shall be

carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer.• DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations between individual

instruments or/and units.
