PARAMETER MEASUREMENT INFORMATION
FPA-slave timing: write cycle
t_M is the cycle time of one-eighth of a local-memory cycle (20.83 ns minimum).
NO.

85 Hold time, address on MAX0, MAX2 after MBCLK1 falling edge, FPA-slave read
86 Setup time, valid address before MBCLK1 falling edge, FPA-slave read
87 Hold time, valid address after MBCLK1 falling edge, FPA-slave read
96 Setup time, valid data/parity after MBCLK1 falling edge, FPA-slave write
97 Hold time, valid data/parity after MBCLK1 falling edge, FPA-slave write
98 Setup time, MDDIR high after MBCLK1 falling edge, FPA-slave write
