I/O

Descriptions

A[11:0]

1, 2, 6:4, 10:8,

97:100

I

Address inputs from the ISA bus.

VDDD

3, 57, 80

I

Digital supply voltage (4.5 to 5.5V).

GNDD

7, 24, 52, 77

I

Digital ground.

AEN

11

I

Active-low address enable from the ISA bus.

D[7:0]

12:19

I/O

Bidirectional data bus. These pins have weak pull-up devices to prevent these inputs from floating

when not driven.

PSEL

20

I

This pin selects the PnP ROM device used:

0

Internal ROM

1

93LC66 – 512 x 8, 9 address bits.

SECS

I/O

Serial EEPROM CS. This is an input pin during RESET.

SEDO

21

I

Data output pin of external PnP serial EEPROM.

VOLDN

I

Active-low volume decrease button input with internal pull-up.

SEDI

22

O

Data input pin to external PnP serial EEPROM.

VOLUP

I

Active-low volume increase button input with internal pull-up.

MUTE

23

I

Active-low mute toggle button input with internal pull-up.

SECLK

O

External serial EEPROM clock output for PnP.

MONO_OUT

25

O

Mono output with source select and volume control (including mute). This pin can drive an external

5k ohm load.

MONO_IN

26

I

Mono input to mixer and ADC. Has an internal pull-up to CMR.
