Section 17 EEPROM
17.4.6
The EEPROM device receives a 7-bit slave address and a 1-bit R/W code following the generation
of the start conditions. The EEPROM enables the chip for a read or a write operation with this
operation.
The slave address consists of a former 4-bit device code and latter 3-bit slave address as shown in
table 17.2. The device code is used to distinguish device type and this LSI uses "1010" fixed code
in the same manner as in a general-purpose EEPROM. The slave address code selects one device
out of all devices with device code 1010 (8 devices in maximum) which are connected to the I
bus. This means that the device is selected if the inputted slave address code received in the order
of A2, A1, A0 is equal to the corresponding slave address reference register (ESAR).
The slave address code is stored in the address H'FF09 in the EEPROM. It is transferred to ESAR
from the slave address register in the memory array during 10 ms after the reset is released. An
access to the EEPROM is not allowed during transfer.
The initial value of the slave address code written in the EEPROM is H'00. It can be written in the
range of H'00 to H'07. Be sure to write the data by the byte write method.
The next one bit of the slave address is the R/W code. 0 is for a write and 1 is for a read.
The EEPROM turns to a standby state if the device code is not "1010" or slave address code
doesn’t coincide.
