Remark The broken line indicates the READY status.
The acknowledge signal is a one-shot pulse generated at the falling edge of SCK0 after 8-bit data transfer.
It can be positioned anywhere and can be synchronized with any clock of SCK0.
After 8-bit data transmission, the transmitter checks whether the receiver has returned the acknowledge
signal. If the acknowledge signal is not returned for the preset period of time after data transmission, it
can be judged that data reception has not been carried out correctly.
