(*1) When using this device at above Ta=25, the power dissipation decreases by 15.9mV per 1rise.  
(*2) This IC is weak against static electricity and surge impulse. Please take counter measure to meet, if  
necessary.  
(*3) This IC is not proofed enough against a strong E-M field by CRT which mau cause function error  
and/or poor characteristics. Keeping the distance from CRT to the IC longer than 20cm, or if cannot,  
placing shield metal over the IC, is recommended in an application.

The read bus flags indicate that a certain signal is

result is not so accurate if checking only one flag, that  
confirming several flags, which means similar result  
by each other, at the same time is recommended.
