EPGM can be read any time and can be written only when ELAT = 1
(for EPROM/OTPROM programming) or when EELAT = 1 (for
EEPROM programming).
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
0 = Programming voltage to EPROM/OTPROM/EEPROM array
1 = Programming voltage to EPROM/OTPROM/EEPROM array
0 = EPROM array configured for normal programming
1 = Program two bytes with the same data
