EEPROM-1 Register Descriptions
6.5.3 EEPROM-1 Nonvolatile Register
The contents of this register is loaded into the EEPROM-1 array configuration register (EE1ACR) after a
reset.
This register is erased and programmed in the same way as an EEPROM byte. (See 6.5.1 EEPROM-1
Control Register for individual bit descriptions).

NOTE
The EE1NVR will leave the factory programmed with $F0 such that the full
array is available and unprotected.
6.5.4 EEPROM-1 Timebase Divider Register
The 16-bit EEPROM-1 timebase divider register consists of two 8-bit registers: EE1DIVH and EE1DIVL.
The 11-bit value in this register is used to configure the timebase divider circuit to obtain the 35 μs
timebase for EEPROM-1 control.
These two read/write registers are respectively loaded with the contents of the EEPROM-1 timebase
divider nonvolatile registers (EE1DIVHNVR and EE1DIVLNVR) after a reset.
