cleared via a read of the SQR register.
Note: When SRST = 1, the chip is in reset state. Read or write to any of the registers is inhibited at this time. The SRST bit is
When this bit is set to "1", a software reset signal is activated. The effects of this reset signal are equivalent to the hardware
These two bits select the output phase delay compensation.
