Notice:
-
Use User Test only for development or evaluation, not for actual use (consumer products). Sensitivity of
this IC may be worse by unexpected noise from monitor pins.
(1)
Register settings in SPI Mode
In SPI User Test Mode, set them as same as normal SPI Mode.
(2)
Register settings in EEPROM Mode
In EEPROM User Test Mode, the register can be set by SPI with connecting EEPROM. In EEPROM
Mode, TC32306FTG as a master reads the register data in EEPROM through SPI lines. But in
EEPROM User Test Mode, this IC as a slave accepts input from SPI lines. In the case, instructions in
SPI format are different from those of SPI Mode. (The MBS “I7” in the instruction is changed from 0 to
1.)

SPI Function Stop
Except above data
* x: 0 or 1
* SPI Function Stop: After writing SPI instruction data, subsequent data input will be disabled. Again, to
enable the input data, enter SPI instruction data correctly after CS pin is set to be "H" once.
Notice:
-
In User Test, must not set MODE2 pin to “L” (= for SPI Mode) to avoid output collision between
TC32306FTG and EEPROM.
-
Take care of chattering to enter User Test by MODE1 pin.
6.9 Status Transition
The Status Transition is carried out after the register value is written. The status after the transition
depends on the register settings. Each status can be moved as following figure by the register settings.
