Description
This signal is not used.
-IOWR is used for control of data write in I/O task file
area. This card does not respond to -IOWR until I/O
card interface setting up.
-IOWR is used for control of data write in I/O task file
area. This card does not respond to -IOWR until True
IDE interface setting up.
-OE is used for the control of reading register’s data in
attribute area or task file area.
-OE is used for the control of reading register’s data in
attribute area.
To enable True IDE mode this input should be
grounded by the host.
The signal is RDY/-BSY pin. RDY/-BSY pin turns low
level during the card internal initialization operation at
VCC applied or reset applied, so next access to the
card should be after the signal turned high level.
This signal is active low -IREQ pin. The signal of low
level indicates that the card is requesting software
service to host, and high level indicates that the card
is not requesting.
This signal is the active high Interrupt Request to the
host.
-REG is used during memory cycles to distinguish
between task file and attribute memory accesses.
High for task file, Low for attribute memory is
accessed.
-REG is constantly low when task file or attribute
memory is accessed.
This input signal is not used and should be connected
to VCC.
