EEPROM STORAGE SEQUENCE (REGISTER 0x0E10 TO REGISTER 0x0E3F)
The default settings of Register 0x0E10 to Register 0x0E33 embody a sample scratch pad instruction sequence. The following is a description
of the register defaults under the assumption that the controller has been instructed to carry out an EEPROM storage sequence.

Description
The default value of this register is 0x08, which the controller interprets as a data instruction. Its
decimal value is 8, which tells the controller to transfer nine bytes of data (8 + 1) beginning at the
address specified by the next two bytes. The controller stores 0x08 in the EEPROM and increments
the EEPROM address pointer.
The default value of these two registers is 0x0100. Note that Register 0x0E11 and Register 0x0E12 are
the most significant and least significant bytes of the target address, respectively. Because the
previous register contains a data instruction, these two registers define a starting address (in this
case, 0x0100). The controller stores 0x0100 in the EEPROM and increments the EEPROM pointer by 2.
It then transfers nine bytes from the register map (beginning at Address 0x0100) to the EEPROM and
increments the EEPROM address pointer by 10 (nine data bytes and one checksum byte). The nine
bytes transferred correspond to the system clock parameters in the register map.
The default value of this register is 0x80, which the controller interprets as an I/O update instruction.
The controller stores 0x80 in the EEPROM and increments the EEPROM address pointer.
Description
The default value of this register is 0xA0, which the controller interprets as a calibrate instruction.
The controller stores 0xA0 in the EEPROM and increments the EEPROM address pointer.
Description
The default value of this register is 0x14, which the controller interprets as a data instruction. Its
decimal value is 20, which tells the controller to transfer 21 bytes of data (20 + 1) beginning at the
address specified by the next two bytes. The controller stores 0x14 in the EEPROM and increments
the EEPROM address pointer.
The default value of these two registers is 0x0200. Note that Register
the most significant and least significant bytes of the target address, respectively. Because the
previous register contains a data instruction, these two registers define a starting address (in this case,
0x0200). The controller stores 0x0200 in the EEPROM and increments the EEPROM pointer by 2. It then
transfers 21 bytes from the register map (beginning at Address 0x0200) to the EEPROM and incre-
ments the EEPROM address pointer by 22 (21 data bytes and one checksum byte). The 21 bytes
transferred correspond to the general configuration parameters in the register map.
Description
The default value of this register is 0x1B, which the controller interprets as a data instruction. Its
decimal value is 27, which tells the controller to transfer 28 bytes of data (27 + 1) beginning at the
address specified by the next two bytes. The controller stores 0x1B in the EEPROM and increments the
EEPROM address pointer.
The default value of these two registers is 0x0300. Note that Register 0x0E19 and Register 0x0E1A are
the most significant and least significant bytes of the target address, respectively. Because the
previous register contains a data instruction, these two registers define a starting address (in this case,
0x0300). The controller stores 0x0300 in the EEPROM and increments the EEPROM pointer by 2. It then
transfers 28 bytes from the register map (beginning at Address 0x0300) to the EEPROM and increments
the EEPROM address pointer by 29 (28 data bytes and one checksum byte). The 28 bytes transferred
correspond to the DPLL parameters in the register map.
