Notice:
-
After reading data reaches the last register address (h’FF), TC32306FTG continues to output
data from the beginning address (h’00).
-
During outputting register value from MISO pin, MOSI pin does not accept input data.
-
To change the instruction or start register address, once set CS pin to be “H” in the Burst
Read/Write.

Confirmation of written data
This function continuously writes data to the order from the specified address and confirms the
written data.
Notice:
-
This function is not intended to read the data inside the register. Use Single/Burst Read mode to
confirm the data inside the register.
Set the Burst Read/Write (Confirmation of written data) data pattern to the register instruction area.
Set same as the Burst Read/Write (Write) and input. The input data is output from MISO pin with 8
bit delay after the address area. The data writing is valid till the rising edge of CS signal, and the data
reading is finished at the rising edge of CS signal.

(The number of write data is same as that of read data.)
