Notes:
1 By measuring the frequency of the internal clock oscillator (see section 9.), the duration of the internal flush and shift periods can be cal-
culated exactly.
2 To achieve the maximum clock frequency, the duty cycle of the read clock has to be 50% with a maximal tolerance of ±5%.
3 The internal oscillator must not be trimmed to a frequency higher than 50MHz.
4 Refer to section 5.6. for more details.
