(read) DATA [ 7:0 ]
(1) The device address consists of signals CS1_N, CS0_N, DA2, DA1 and DA0.
(2) The data bus width depends on the PIO access command used. The Task File register access uses 8 bits (DATA[7:0]), except
(3) The device can negate READY/IORDY to extend the PIO cycle with wait states. The host determines whether or not to extend
(4) DIOR and DIOW have a programmable polarity: shown here as active LOW signals.
