+ *
+ * 1) Since both ESCR and CCCR registers have only low

+ * configuration. Low 32 bits of such config correspond
+ * to low 32 bits of CCCR register and high 32 bits

+ *
+ * 2) The meaning of every bit of such config field can

+ * we "borrow" some reserved bits for own usage and
+ * clean them or set to a proper value when we do
+ * a real write to hardware registers.
+ *
+ * 3) The format of bits of config is the following
+ * and should be either 0 or set to some predefined
+ * values:

+ * Low 32 bits
