NOTE:
NOTE:
Bit 6 from high byte of SHADOW word should not be programmed in
order to have the full EEPROM array visible.
EESWAI — EEPROM Stops in Wait Mode
The EESWAI bit should be cleared if the WAIT mode vectors are
mapped in the EEPROM array.
PROTLCK — Block Protect Write Lock
DMY— Dummy bit
Freescale Semiconductor, Inc.
the high byte of the SHADOW word, $0FC0, are loaded to
EEMCR[7:4]. Bits[1:0] from the high byte of the SHADOW word,
$0FC0,are loaded to EEDIVH[1:0]. Bits[7:0] from the low byte of the
SHADOW word, $0FC1,are loaded to EEDIVL[7:0]. BULK
program/erase only applies if SHADOW word is enabled.
Read and write anytime.
Read anytime. Write once in normal modes (SMODN = 1), set and
clear any time in special modes (SMODN = 0).
Read and write anytime.
For More Information On This Product,
0 = The module is not affected during WAIT mode
1 = The module ceases to be clocked during WAIT mode
0 = Block protect bits and bulk erase protection bit can be written
1 = Block protect bits are locked
