6.6 EEPROM-1 Register Descriptions
6.6.1 EEPROM-1 Control Register
MC68HC908AZ60A — Rev 2.0
MOTOROLA
Address:
Four I/O registers and three non-volatile registers control program, erase
and options of the EEPROM-1 array.
This read/write register controls programming/erasing of the array.
Bit 7— Unused bit
EEOFF — EEPROM-1 power down
EERAS1 and EERAS0 — Erase/Program Mode Select Bits
Reset:
Read:
Write:
This read/write bit is software programmable but has no functionality.
This read/write bit disables the EEPROM-1 module for lower power
consumption. Any attempts to access the array will give unpredictable
results. Reset clears this bit.
These read/write bits set the erase modes. Reset clears these bits.
1 = Disable EEPROM-1 array
0 = Enable EEPROM-1 array
X = don’t care
