1) Standard ROM Check
Check contents
The standard ROM area (200000H ∼ 3FFFFFH) is added in the
unit of byte. If the lower two digits of the result is 20H, it is normal.
The ROM version and the model name code which are stored in
address 31FFE0H ∼ 31FFFFH where the ROM version and the
check sum correction data stored are displayed. The format of
data (ASCII) to be stored is as follows:
31FFE0H ∼ 31FFEFH: Model name code (example: UP-3300,
Display is made up to 00H of data.)
31FFF0H ∼ 31FFF9H: 27801R****(****=PROGRAM VERSION)
31FFFAH ∼ 31FFFBH: BLOCK NO. ("20" ∼ "3F")
31FFFCH: TERMINATOR ("=")
31FFFDH ∼ 31FFFEH: BLOCK VERSION (example "00")
31FFFFH: CHECK SUM CORRECTION DATA
The flash ROM used as the standard ROM has rewriting block of
64KB as the unit. To control the version in each block, the compo-
sition is the same as the above 31FFF0H or later and arranged in
each 64KByte. At that time, correction is made so that the sum of
each block becomes 01H, and the total of 2MByte is 20H.
The FLASH write MASTER EPROM has changed from 8 Mbits to
2 chips so that the program version indication can be managed by
each chip. The program version stored in the blocks of 21H and
31H is displayed.
The program version of the IPL is displayed so that 0PAGE where
the IPL is stored is individually controlled.

2) SERVICE ROM Check
Note: This check should only be performed will be using the service
ROM.
Check content
The standard ROM (EPROM × 2 Chip) area (D00000H ~
EFFFFFH) is added in the unit of byte. If the lower two digits of
the result is 10H, it is normal. The ROM version and the model
name code which are stored in address D1FFE0H ~ D1FFFFH
where the ROM version and the check sum correction data are
stored are displayed. The format of data (ASCII) to be stored is as
follows:
D1FFE0H ∼ D1FFEFH: Model name code (example: UP-3300.
Display is made up to 00H of data.)
D1FFF0H ∼ D1FFF9H: 27801R****(****=PROGRAM VERSION)
D1FFFAH ∼ D1FFFBH: BLOCK NO. ("20" ∼ "2F")
D1FFFCH: TERMINATOR ("=")
D1FFFDH ∼ D1FFFEH: BLOCK VERSION (example "00")
D1FFFFH: CHECK SUM CORRECTION DATA
This SERVICE ROM allows to write into the FLASH ROM when
re-execution is impossible because of an abnormality during re-
writing into the FLASH ROM. The composition is the same as the
standard ROM.
The program version of the IPL is displayed so that 0PAGE where
the IPL is stored is individually controlled.
