Operating Modes and On-Chip Memory
3.6 EPROM, EEPROM and CONFIG register
3.6.1 EPROM
3.6.1.1 EPROG — EPROM programming control register
Technical Data
EPROM programming (EPROG) $002B
Using the on-chip EPROM programming feature requires an external
power supply (V
EPROG register. Program EPROM at room temperature only and place
an opaque label over the quartz window after programming.
The erased state of each EPROM byte is $FF.
MBE — Multiple byte program enable
Bits 6, 2, 1 — Not implemented; always read zero.
ELAT — EPROM latch control
Freescale Semiconductor, Inc.
When programming four bytes simultaneously, address bits 7 and 4
are ignored, hence a write to, for example, $99 will actually program
$09, $19, $89 and $99 (i.e. %x00x 1001). This bit may be read or
written only in special modes; it will always read zero in normal
modes.
When set, this bit causes the address and data for writes to the
EPROM to be latched. ELAT may be read and written at any time.
