drain, push-pull or output disable)

— Programmable option for internal pull-up resistor on

each input pin

— Output lock option

— Input debounce mechanism

• Fan Speed Control and Fan Speed Monitor (FSCM)

— Supports different fan types

— Speed monitoring for three fans

t Digital ﬁltering of the tachometer input signal

plementation of AT and PS/2 drive types

— 16-byte FIFO

— Software compatible with the PC8477, which con-

tains a superset of the FDC functions in the

microDP8473, the NEC microPD765A and the

N82077

— High-performance, digital separator

iﬁcation

— EPP support as mode 4 of the Extended Capabilities

Port (ECP)

— IEEE 1284 compliant ECP, including level 2

— Selection of internal pull-up or pull-down resistor for

Paper End (PE) pin

— PCI bus utilization reduction by supporting a de-

mand DMA mode mechanism and a DMA fairness

mechanism

— Protection circuit that prevents damage to the paral-

lel port when a printer connected to it powers up or

is operated at high voltages, even if the device is in

power-down

— Output buffers that can sink and source 14 mA

• Serial Port 1 (UART1)

— Software compatible with the 16550A and the 16450
