MOTOROLA
CAUTION:
NOTE:
EEDIV[9:0] — Prescaler divider
An incorrect or uninitialized value on EEDIV can result in overstress of
EEPROM array during program/erase operation. It is also strongly
recommend not to program EEPROM with oscillator frequencies less
than 250 Khz.
INT[A] denotes the round down integer value of A. Program/erase cycles
will not be activated when EEDIV = 0.
Loaded from SHADOW word at reset.
Read anytime. Write once in normal modes (SMODN =1) if EELAT =
0 and anytime in special modes (SMODN =0) if EELAT = 0.
The prescaler divider is required to produce a self-time clock with a
fixed frequency around 28.6 Khz for the range of oscillator
frequencies. The divider is set so that the oscillator frequency can be
divided by a divide factor that can produce a 35 µs +/- 2µs pulse.
The EEDIV value is determined by the following formula:
