EEPROM Memory
9.7 Shadow Word Mapping
Technical Data
134
The shadow word is mapped to location $_FC0 and $_FC1 when the
NOSHW bit in EEMCR register is zero. The value in the shadow word is
loaded to the EEMCR, EEDIVH and EEDIVL after reset.
shows the mapping of each bit from shadow word to the registers.
1. Reserved for testing. Must be set to one in user application.
2. Reserved. Must be set to one in user application for future compatibility.
