2) The master clock period is the base for all time measurements without stand-by. Relative tolerances of all performed time
measurements are same as with tMCLK
.
3) The stand-by clock is the base for all time related characteristics during stand-by operation.
4) Phase for loading the OTP content to the internal RAM

1) Not tested in production test.
2) Min. and max. values are based on stand-by clock period tSTBCLK limits (see Table 20).
3) Min. and max. values are based on master clock period tMCLK (see Table 20).
4)
The recommended temp is below 125 ˚C, above this temperature, IC function cannot be guaranteed, Customer should guarantee
the design will never exceed the 125 ˚C of IC die temperature.
