Where the result inside the bracket is rounded down to the nearest
integer value.
For example, if the reference frequency is 4.9152MHz, the EEDIV
value is 172.
NOTE: Programming/erasing the EEPROM with an improper EEDIV value may
result in data lost and reduce endurance of the EEPROM device.
5.11.3.1 EEPROM Timebase Divider Mask Option Register
The 16-bit EEPROM timebase divider mask option register consists of
two 8-bit read-only registers: EEDIVHMOR and EEDIVLMOR. The
contents of these two registers are respectively loaded into the
EEPROM timebase divider registers, EEDIVH and EEDIVL, after a
reset.
These two registers are hard-wired connections specified at the same
time as the ROM code.
