DP8473 Implementation into the PS/2 Floppy Controller Design

• OPI/64 and OPI/16 three-microprocessor configuration - includes a display microprocessor that controls aU display functions; an input/output microprocessor that

The other input is either a reference frequency (derived from the Reference Clock) of twice the data rate while the data separator is in the idle mode, or when reading the disk

Since a floppy controller design may not work cor- rectly due to current overloading, it is important to understand exactly how to calculate the maximum current required by the

The Data Conditioner function is to stretch the narrow Read Signal pulses from the floppy so that they will overlap the microprocessor's clock interval,

The processor generates DISK DRIVE COMMANDS by manipulating bits in the uPD372 write registers and the DISK DRIVE STATUS signals control the state of bits in

When operating from internal program memory, these pins are the output data and strobes to an external serial EEPROM that contains manufacturer specific ID and string
