Operating Modes and On-Chip Memory
Data Sheet

Bit 6 — Unimplemented
ELAT — EPROM/OTPROM Latch Control Bit
EXCOL — Select Extra Columns Bit
EXROW — Select Extra Rows Bit
T[1:0] — EPROM Test Mode Select Bits
PGM — EPROM Programming Voltage Enable Bit
Always reads 0
When ELAT = 1, writes to EPROM cause address and data to be latched and
the EPROM/OTPROM cannot be read. ELAT can be read any time. ELAT can
be written any time except when PGM = 1; then the write to ELAT is disabled.
These bits allow selection of either gate stress or drain stress test modes. They
can be read and written only in special modes and always read 0 in normal
modes.
PGM can be read any time and can be written only when ELAT = 1.
0 = EPROM/OTPROM address and data bus configured for normal reads
1 = EPROM/OTPROM address and data bus configured for programming
0 = User array selected
1 = User array is disabled and extra columns are accessed at bits [7:0].
0 = User array selected
1 = User array is disabled and two extra rows are available. Addresses use
0 = Programming voltage to EPROM array disconnected
1 = Programming voltage to EPROM array connected

For More Information On This Product,
Addresses use bits [13:5] and bits [4:0] are don’t care. EXCOL can be
read and written only in special modes and always returns 0 in normal
modes.
bits [7:0] and bits [13:8] are don’t care. EXROW can be read and written
only in special modes and always returns 0 in normal modes.
