Description

22

I2DAT

I2C Data – This data line supports the I2C bus which supports external slave

 

 

devices only. The interface I2C bus is intended for support of EEPROMs

 

 

and other simple I/O-devices. The data rate is approximate 1-10kHz.

23

SMBCLK

System Management Bus Clock – This signal is used to support internal

 

 

and external SMBus devices, such as temperature and battery monitoring.

24

SMBDATA

System Management Bus Data – This signal is used to support internal and

 

 

external SMBus devices, such as temperature and battery monitoring.

PIDE_A2

Primary Drive Address Bus 2 – Used (0 to 2) to indicate which byte in the

 

 

ATA command block or control block (register) is being accessed.

37

NC

Not Connected (SIDE_A1)

 

 

 

38

PIDE_A0

Primary Drive Address Bus 0 – Refer to PIDE_A2, pin-36, for more

 

 

information.

40

PIDE_A1

Primary Drive Address Bus 1 – Refer to PIDE_A2, pin-36, for more

 

 

information.

41

BATLOW*

Battery Low – This external signal to the XTX 820 indicates when the

 

 

external battery is low.

42

GPE1*

General Purpose Power Management Event Input 1 – This signal may be

 

 

driven low by external circuitry to signal an external power management

 

 

event. This pin is commonly connected to the chipset’s LID# input.

43

NC

Not Connected (SIDE_AK*)

44

PIDE_INTRQ

Primary Drive Interrupt Request (IRQ 14)– Asserted by drive when it has

 

 

pending interrupt (PIO transfer of data to or from the drive to the host).

45

NC

Not Connected (SIDE_RDY)

46

PIDE_AK*

Primary DMA Channel Acknowledge – Used by the host to acknowledge

 

 

data has been accepted or data is available. Used in response to

 

 

PIDE_DMARQ asserted.

47

NC

Not Connected (SIDE_IOR*)

 

 

 

48

PIDE_RDY

Primary I/O Channel Ready – When negated extends the host transfer cycle

 

 

of any host register access when the drive is not ready to respond to a data

 

 

transfer request. High impedance if asserted.

49

VCC2

+5 volts +/-5%
