EEPROM Erasing
68HC908AZ32A — Rev 0.0
MOTOROLA
NOTE:
NOTE:
D. The delay time for the EEPGM bit to be cleared in AUTO mode is less
than t
For forward compatibility, software should not make any dependency on
this delay time.
E. Any attempt to clear both EEPGM and EELAT bits with a single
instruction will only clear EEPGM. This is to allow time for removal of
high voltage from the EEPROM array.
The programmed state of an EEPROM bit is logic 0. Erasing changes
the state to a logic 1. Only EEPROM bytes in the non-protected blocks
and the EENVR register can be erased.
Use the following procedure to erase a byte, block or the entire
EEPROM array:
If using the AUTO mode, also set the AUTO bit in Step 1.
A. Setting the EELAT bit configures the address and data buses to latch
data for erasing the array. Only valid EEPROM addresses will be
latched. If EELAT is set, other writes to the EECR will be allowed after a
valid EEPROM write.
1. Configure EERAS1 and EERAS0 for byte, block or bulk erase; set
2. Byte erase: write any data to the desired address.
3. Set the EEPGM bit.
4. Wait for a time: t
5. Clear EEPGM bit.
6. Wait for a time, t
7. Poll the EEPGM bit until it is cleared by the internal timer.
8. Clear EELAT bits.
