The operations above are managed by using the
internal 4-bit EPROM Control Register. The
reading phase is executed with V
the verify/Margin Mode phase needs V
12V 5%. The Blank Check must be a reading
operation with V
Table 3.2 illustrates EPROM Control Register
codes used to identify the operation running.
3.1 EPROM Programming Phase Procedure
The Programming mode is selected by applying
12V 5% voltage or 5V 5% voltage to the V
and setting the control signal as following:
RESET =Vss
TEST =Vss
If the V
performed.
RST_ADD, INC_ADD, RST_CONF, INC_CONF
and PHASE are the control signals used during the
Programming Mode.
PHASE, RST_CONF and RST_ADD signals are
active on level, the others are active on rising
edge.
