The first letter in each registration indicates the timing of the line.

A => the decoder emits a pulse with timing identical to PhA.

B => the decoder emits a pulse with timing identical to PhB.

BA => the decoder emits a level which changes on the rising edge of PhB.

AB => the decoder emits a level which changes on the rising edge of PhA.

DA => the decoder emits a pulse with timing identical to PhA during the PhA following the first PhA that the word comes out of the ROM.
