Auto clock monitoring bit (CNTFLG)
This bit sets "1" when the clock restoration process is being executed by the controller. This bit is modified from "0" to
"1" when the clock restoration process by the controller is started, and after the clock is restored and when "SCKE=1",
"1" is modified to "0".
This bit enables or disables the falling edge of CS_N as an event to shift the controller from low power sleep mode to
normal status. Refer to Table 2.7 for the difference in restoration events according to the setup value of this bit.
