26. Module: Data EEPROM
FIGURE 1:
DS80453E-page 20
The Most Significant bit of every fourth byte in data
EEPROM may be corrupted on any write
operation. This write corruption may occur while
using either PRO MATE
Run-Time Self-Programming (RTSP).
Figure 1
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
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.
