Bits [2:1] —Not implemented
EPGM —EPROM Programming Voltage Enable
20
MOTOROLA
Always read zero
EPGM can be read any time and can only be written when ELAT = 1.
0 = User array selected
1 = User array is disabled and extra columns are accessed at bits [7:0]. Addresses use bits [11:5]
0 = User array selected
1 = User array is disabled and two extra rows are available. Addresses use bits [5:0] and bits [11:6]
0 = Programming voltage to EPROM array disconnected
1 = Programming voltage to EPROM array connected
and bits [4:0] are don't care. EXCOL can only be read in special modes and always returns zero
in normal modes. EXCOL can be written in special modes only.
are don't care. EXROW can only be read in special modes and always returns zero in normal
modes. EXROW can be written in special modes only.
