ELAT — EPROM Latch Control Bit
EXCOL — Select Extra Columns Bit
EXROW — Select Extra Rows Bit
EPGM — EPROM Programming Enable Bit
Setting ELAT latches the address and data of writes to the EPROM.
The EPROM cannot be read. ELAT can be read at any time. ELAT
can be written any time except when PGM = 1, which disables writes
to ELAT.
EXCOL is for factory use only and is accessible only in special test
mode. When EXCOL equals 1, extra columns can be accessed at
bit 7 and bit 0. Addresses use bits [11:5]. Bits [4:1] are ignored.
EXROW is for factory use only and is only accessible in special test
mode. When EXROW equals 1, two extra rows are available.
Addresses use bits [5:0]. Bits [11:6] are ignored.
EPGM applies programming voltage (V
be read at any time. EPGM can be written only when ELAT = 1.
