*1 Тип сигнала для устройства: I -
вход, O - выход, I/O - двунаправленный,
TS - тристабильный, OK - открырый кол-
лектор.
*2 У старых устройств сигнал может
иметь тип OK (при разнотипных сигналах на
одной шине возможенconflict)
*3 Device-0 has an input, device-1 has an input
-- exit
*4 Device-1 has only output
Pins 41-44 are used for mini-
turkish discs
Reset# - device reset
DA 2-0 - three least significant bits of the system bus
These are the addresses used to select the re-
device girs
D 0-15 - bidirectional data bus
DIOR# - strobe for reading input/output ports
yes. Data is recorded on the positive
signal drop
DIOW# - the same, for recording
IORDY - device readiness to complete
exchange cycle. Low signal level during
exchange cycle time the device can
enter bus wait cycles
IOCS16# - resolution of 16-bit operating
tions. Access to all registers except
data register, always 8-bit.
DMARQ - exchange request over a DMA channel
(signal optional)
DMACK# - DMA confirmation
INTRQ - interrupt request. The output must
be tristable, active signal -
log. 1.
CSO# - select command register block
CS1# - selection of control relay block
histrov
PDIAG# - signal about passing diagnostics
tics. Signalserves only to connect two
devices, and the host adapter is not used
enjoys.
DASP# - dual purpose signal: in-
device activity indicator and
presence of device-1. The devices have
output type "open collector" with load
a 10 kOhm resistor to the +5 V bus.
The adapter uses this signal to turn on
Readings of the LED access indicator
disk.
SYSIN/CSEL - spindle/synchronization
- cable harness.

A number of ATA (AT IDE) devices have a jam-
lane, switching operating mode XT/AT (in
Seagate drives for this possibility
ness indicates the ending AX in the notation
ni model)
