Operating Modes and On-Chip Memory
MBE — Multiple-Byte Programming Enable Bit
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

When multiple-byte programming is enabled, address bit 5 is considered a don’t care so that bytes with
address bit 5 = 0 and address bit 5 = 1 both get programmed. MBE can be read in any mode and
always reads 0 in normal modes. MBE can be written only in special modes.
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.
0 = EPROM array configured for normal programming
1 = Program two bytes with the same data
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]. Addresses use bits [13:5]
0 = User array selected
1 = User array is disabled and two extra rows are available. Addresses use bits [7:0] and bits [13:8]
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.
are don’t care. EXROW can be read and written only in special modes and always returns 0 in
normal modes.
