Technical Manual
5.5.6. Connector X1203 (Secondary IDE)
All signals are LVTTL compatible.
PIDE_D0...15
Secondary IDE ATA data bus. These are the data pins connected to secondary channel.
PIDE_A0...2
Secondary IDE ATA address bus. These are the address pins connected to secondary channel.
PIDE_CS0#
IDE Chip Select 1 for secondary channel 0. This is the Chip Select 1 command output pin to enable the
secondary IDE device to watch the read/write command.
PIDE_CS1#
IDE Chip Select 3 for secondary channel 1. This is the Chip Select 3 command output pin to enable the
secondary IDE device to watch the read/write command.
SIDE_DRQ
Secondary IDE DMA Request for IDE Master. This is the input pin from the secondary channel IDE DMA
request to do the IDE Master transfer.
SIDE_DACK#
Secondary IDE DACK for IDE Master. This is the output pin to grant the secondary channel IDE DMA
request to begin the IDE Master transfer.
SIDE_IORDY
Secondary IDE Ready. This is the input pin from the secondary IDE channel to indicate the IDE device is
ready to terminate the IDE command in PIO mode. The IDE device can deassert this input (logic 0) to
expand the IDE command if the device is not ready.
SIDE_IOR#
Secondary IDE IOR command. This is the IOR command output pin to notify the secondary IDE device to
assert the read data in PIO and DMA mode.
SIDE_IOW#
Secondary IDE IOW command. This is the IOW command output pin to notify the secondary IDE device
that the available write data is already asserted by IDE Busmaster in PIO and DMA mode.
DASP_P
Time-multiplexed, open collector output which indicates that a drive is active, or that a slave drive is
present on secondary IDE channel. Necessary for using IDE master/slave-mode on secondary IDE
channel.
PDIAG_P
Output by the drive if it is jumpered in the slave mode; input to the drive if it is jumpered in the master
mode. The signal indicates to a master that the slave has passed its internal diagnostic command.
Necessary for using IDE master/slave-mode on secondary IDE channel.
PIDE_RST#
Low active hardware reset (RSTDRV inverted).
SIDE_IRQ
Secondary channel interrupt signal.
