The Most Significant bit of every fourth byte in data
EEPROM may be corrupted on any write opera-
tion. This write corruption may occur while using
either PRO MATE
Self-Programming (RTSP).
Figure 1 shows the first twelve bytes in data
EEPROM and indicates the affected bits.
Work arounds
Work around 1:
Use program Flash memory instead of data
EEPROM to store constant data.
Work around 2:
Use less than 16 bits in each word in the available
word of data EEPROM, excluding the Most
Significant bit.
(Odd Address)
Note 1: The shaded bits labelled “B” represent the bits that may be corrupted on a write operation.

Work around 3:
Avoid using every fourth byte. Example 11 shows
how the ASM30 assembler can be used to allocate
data in the EEPROM under this constraint.
