1.2.2
Writing Method for General-purpose PROM Program
(1)
Adapters
BM11127 : TMP87PP24AF
(2)
Adapter setting
Switch (SW1) is set to side N.
(3)
PROM programmer specifying
i)
PROM type is specified toTC571000D.
Writing voltage:
12.75 V (high-speed program mode)
ii)
Data transfer (copy) (note 1)
In
the
TMP87PP24A,
EPROM
is
within
the
addresses
14000
h
to
IFFFF
h
.
Data
is
required
to
be
transferred
(copied)
to
the
addresses
where
it
is
possible
to
write.
The
program
area
in
MCU
mode and PROM mode is referred to "Program memory area" in Figure 1-1.
Ex. In the block transfer (copy) mode, executed as below.
ROM capacity of 48KB : transferred addresses 04000
h
to OFFFF
h
to addresses 14000 to IFFFF
h
iii)
Writing address is specified. (Note 1)
Start address
:14000
h
End address :
IFFFF
h
(4)
Writing
WritingA/erifying is required to be executed in accordance with PROM programmer operating
procedure.
Note
1:
The
specifying
method
is
referred
to
the
PROM
programmer
description.
Either
write
the
data FF
h
to the unused area or set the PROM programmer to access only the program
storage area.
Note 2 : When MCU is set to an adapter or the adapter is set to PROM programmer, a position of pin
1 must be adjusted. If the setting is reversed, MCU, the adapter and PROM program is
damaged.
Note 3 : The TMP87PP24A does not support the electric signature mode (hereinafter referred to as
"signature"). If the signature is used in PROM program, a device is damaged due to applying
12V ± 0.5V to the address pin 9 (A9). The signature must not be used.
