Notes on Microprocessor Interface Write Timing:
1
A valid write cycle is defined as a logical OR of the CSB and the WRB signals.
2. Microprocessor Interface timing applies to normal mode register accesses only.
3. When a set-up time is specified between an input and a clock, the set-up time is
the time in nanoseconds from the 1.4 Volt point of the input to the 1.4 Volt point of
the clock.
