==============================================================================
##### DelayBlock peripheral features #####
==============================================================================
[..] The Delay block is used to generate an Output clock which is de-phased from the Input
clock. The phase of the Output clock is programmed by FW. The Output clock is then used
to clock the receive data in i.e. a SDMMC or QSPI interface.
The delay is Voltage and Temperature dependent, which may require FW to do re-tuning
and recenter the Output clock phase to the receive data.
[..] The Delay Block features include the following:
(+) Input clock frequency range 25MHz to 208MHz.
(+) Up to 12 oversampling phases.
##### How to use this driver #####
==============================================================================
[..]
This driver is a considered as a driver of service for external devices drivers
that interfaces with the DELAY peripheral.
The DelayBlock_Enable() function, enables the DelayBlock instance, configure the delay line length
and configure the Output clock phase.
The DelayBlock_Disable() function, disables the DelayBlock instance by setting DEN flag to 0.
