MOTOROLA
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 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/OTPROM address and data bus configured for normal
1 = EPROM/OTPROM address and data bus configured for
0 = User array selected
1 = User array is disabled and extra columns are accessed at bits
0 = User array selected
1 = User array is disabled and two extra rows are available.

[7:0]. 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.
Addresses use 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.
