Rev. 1.1
Note: Non-volatile EEPROM register; write by programming.
Address:
EEBP[3:0] — EEPROM Block Protection Bits
The contents of this register is loaded into the EEPROM array
configuration register (EEACR) after a reset.
This register is erased and programmed in the same way as an
EEPROM byte.
The EENVR is factory programmed with $10.
The 16-bit EEPROM timebase divider register consists of two 8-bit
registers: EEDIVH and EEDIVL. The 11-bit value in this register is used
to configure the timebase divider circuit to obtain the 35µs timebase for
EEPROM control.
Reset:
Read:
Write:
These bits prevent blocks of EEPROM array from being programmed
or erased.
1 = EEPROM array block is protected
0 = EEPROM array block is unprotected
