Value

Controlling

Variable

t1(min) = time_1 * T – (tskew1 + tskew2 + tskew5)

time_1

t2 (read)

t2r

t2(min) = time_2r * T – (tskew1 + tskew2 + tskew5)

time_2r

t9(min) = time_9 * T – (tskew1 + tskew2 + tskew6)

time_9

t5(min) = tco + tsu + tbuf + tbuf+ tcable1 + tcable2

time_2 (affects tsu and

tco)

—

tA(min) = (1.5 + time_ax) * T – (tco + tsui + tcable2 + tcable2 + 2*tbuf)

time_ax

trd

trd1

trd1(max) = (–trd)+ (tskew3 + tskew4)

trd1(min) = (time_pio_rdx – 0.5)*T – (tsu + thi)

(time_pio_rdx – 0.5) * T > tsu + thi + tskew3 + tskew4

time_pio_rdx

—

t0(min) = (time_1 + time_2r+ time_9) * T

time_1, time_2r, time_9
