MITSUBISHI <DIGITAL ASSP>
Output Qn of n cycle <1>* can be read until the start of reading side n cycle <1> and the start of writing side n cycle <2>* overlap each
other.
Reading shortest n-cycle write data "n"
(Reading side n-1 cycle starts after the end of writing side n-1 cycle.)

When the reading side n-1 cycle starts before the end of the writing side n+1 cycle, output Qn of n cycle is made invalid.
In the following diagram, reading operation of n-1 cycle is invalid.
Reading longest n-cycle write data "n": 1 line delay
(When writing side n-cycle <2>* starts, reading side n cycle <1>* then starts.)
