Problem
An R error occurs although the final
page is passed.
Activation is impossible.
The evaluation board does not work
when it is used independently.
Target segment does not light.
Remedy measures
The cross assembler is designed to output "R error" every
time the page is changed. Use a pseudo-instruction to set
the memory, such as ORG or PAGE, to change the page.
See "Memory setting pseudo-instructions" in the cross
assembler manual.
Check the following and remedy if necessary:
• Is the number of files set at ten or more in OS environ-
ment file CONFIG.SYS?
Check the following and remedy if necessary:
• Has the EPROM for F.HEX and S.HEX been replaced
by the EPROM for the target?
• Is the EPROM for F.HEX and S.HEX installed correctly?
• Is the appropriate voltage being supplied? (5V DC, 3A,
or more)
• Are the program ROMs (H and L) installed correctly?
• Is data written from address 4000H? (When the 27C256
is used as the program ROM)
Check the following and remedy if necessary:
• Is an EPROM with an access time of 250 ns or less being
used for S.HEX.
