REGISTER BIT CROSS REFERENCE
Table 120 shows the location and default value for each
programmable bit or field. The Offset column gives the
offset in hexadecimal of the register that contains the
bit. The codes in the Reset Type column have the fol-
lowing meanings:

Hardware Reset. The bit is set to its default
value when the RST pin is asserted (low).
EEPROM Reset. The bit is set to its default
value when before the EEPROM is read or after
an EEPROM read error is detected
Power On Reset. The bit is set to its default
value when power is first applied to the device.
