7.5.3 EEPROM-2 Nonvolatile Register
The contents of this register is loaded into the EEPROM-2 array configuration register (EE2ACR) after a
reset.
This register is erased and programmed in the same way as an EEPROM byte. (See
Control Register
7.5.4 EEPROM-2 Timebase Divider Register
The 16-bit EEPROM-2 timebase divider register consists of two 8-bit registers: EE2DIVH and EE2DIVL.
The 11-bit value in this register is used to configure the timebase divider circuit to obtain the 35 μs
timebase for EEPROM-2 control.
These two read/write registers are respectively loaded with the contents of the EEPROM-2 timebase
divider nonvolatile registers (EE2DIVHNVR and EE2DIVLNVR) after a reset.
