NOTES

References to WR also pertain to WRH

1 Definition of ‘‘read cycle without a previous write’’ The time between the rising edge of WR WRH (for the previous

write cycle) and the falling edge of RD (for the current read cycle) is greater than 2 tMCLK

2 Definition of ‘‘write cycle with a previous write’’ The time between the rising edge of WR WRH (for the previous write

cycle) and the rising edge of WR WRH (for the current write cycle) is less than 2 tMCLK

3 Definition of CDV is the value loaded in the CLKOUT register representing the CLKOUT divisor
