EEPROM User Test Mode
SPI Mode and EEPROM Mode have a difference about an external connection, pin functions and control
signal flows. Do not change the Mode settings in the market products.

6.2.1 SPI Mode Setting and Connection
MCU and TC32306FTG are connected by SPI lines and MCU controls this IC.
Fig 6-4 Conceptual Connection MCU and TC32306FTG
6.2.2 EEPROM Mode Setting and Connection
EEPROM and MCU, connect via TC32306FTG. This IC is controlled by the register data of EEPROM.
Select up to 8 configuration that are made as registers from “h'0A” to “h'1C”, depending on the size of
EEPROM. In this mode, use of pins and external connections are different from those of SPI Mode. For
example, TX_SW / RX_SW / ENB pin are used to select configuration of EEPROM.
