Notes: (1) Either t₁ (a –w) or t₁ (a –c) should be satisfied.
(2) t₁ is defined depending upon CS or WR which becomes active last.
(3) 3-clock time of oscillation clock (clock period: 21ns). It is required for increment of FIFO.
(4) 2-clock time of oscillation clock (clock period: 21ns). It is required for increment of FIFO.
(5) Applied to all registers including CLRFIFO (address: 4Eh).
