17.2
Pins used in the EEPROM are listed in table 17.1.
Table 17.1 Pin Configuration
17.3
The EEPROM has a following register.
• EEPROM key register (EKR)
17.3.1
EKR is an 8-bit readable/writable register, which changes the slave address code written in the
EEPROM. The slave address code is changed by writing H'5F in EKR and then writing either of
H'00 to H'07 as an address code to the H'FF09 address in the EEPROM by the byte write method.
EKR is initialized to H'FF.

Function
The SCL pin is used to control serial input/output data timing.
The data is input at the rising edge of the clock and output at
the falling edge of the clock. The SCL pin needs to be pulled
up by resistor as that pin is open-drain driven structure of the

20.2.2, DC Characteristics and in section 20.2.3, AC
Characteristics. Maximum clock frequency is 400 kHz.
The SDA pin is bidirectional for serial data transfer. The SDA
pin needs to be pulled up by resistor as that pin is open-drain
driven structure. Use proper resistor value for your system by
considering V
20.2.2, DC Characteristics and in section 20.2.3, AC
Characteristics. Except for a start condition and a stop
condition which will be discussed later, the high-to-low and
low-to-high change of SDA input should be done during SCL
low periods.
