Function 1 Control Registers
These configuration registers control various features of the W83C553F and the IDE interface. Reserved registers are
hardwired to a 00h and cannot be programmed. The first register controls the general features of the W83C553F and both
IDE ports. The next four registers control the features and timing of the 4 individual IDE devices. All features of the IDE
interface that have no effect on the performance of the mass storage subsystem have been set to fixed values in hardware (i.e.;
all 8-bit timing).
