#. Note :

1. Internal system is reset at VPP = 12.5V and K2=`Low`

2. OSC1 is made of a block of 8 x Tp clock.

3. From this time when the reset is released (K2=`High`) , OSC1 clock is counted by 1-bolck.

4. If not written during 10 times repeats (120us), repeat the 5 times until all is written.

5. For device verify. If you set Lock bit, output data is always `0F`h.
