Note that these options are not determined until the option setting period of about 1 ms, which follows a period of about
75 ms from power application, has passed.
3. Use of the mass produced unit printed circuit board
When using the printed circuit board for the massed produced end product with the LC72E32, be sure to connect the
TEST1 and TEST2 pins to VSS and be sure to connect both pins 31 and 73 (the VDD pins) to the plus side of the
power supply.
4. EPROM address space
Note: Due to their structure, on-chip EPROM microcontrollers (products in which the EPROM has not been written)
cannot be fully tested prior to shipment. As a result, the yield after writing may be decreased.
