Description
IDE Reset. This signal resets all devices attached to the
IDE interface.
IDE Address Bits. These address bits are used to
access a register or data port in a device on the IDE bus.
IDE Data Lines. IDE_DATA[15:0] transfers data to/from
the IDE devices.
IDE I/O Read Channels 0 and 1. IDE_IOR0# is the read
signal for Channel 0 and IDE_IOR1# is the read signal
for Channel 1. Each signal is asserted at read accesses
to the corresponding IDE port addresses.
IDE I/O Write Channels 0 and 1. IDE_IOW0# is the
write signal for Channel 0. IDE_IOW1# is the write signal
for Channel 1. Each signal is asserted at write accesses
to corresponding IDE port addresses.
IDE Chip Selects 0 and 1. These signals are used to
select the command block registers in an IDE device.
I/O Ready Channels 0 and 1. When de-asserted, these
signals extend the transfer cycle of any host register
access if the required device is not ready to respond to
the data transfer request.
Note:
DMA Request Channels 0 and 1. The IDE_DREQ sig-
nals are used to request a DMA transfer from the
SC1200/SC1201 processor. The direction of transfer is
determined by the IDE_IOR/IOW signals.
Note:
DMA Acknowledge Channels 0 and 1. The
IDE_DACK# signals acknowledge the DREQ request to
initiate DMA transfers.
Interrupt Request Channels 0 and 1. These input sig-
nals are edge-sensitive interrupts that indicate when the
IDE device is requesting a CPU interrupt service.
Note:
If selected as IDE_IORDY0 or IDE_IORDY1
function(s) but not used, then signal(s) should be
tied high.
If selected as IDE_DREQ0/ IDE_DREQ1 func-
tion but not used, tie IDE_DREQ0/IDE_DREQ1
low.
If selected as IRQ14/IRQ15 function but not
used, tie IRQ14/IRQ15 low.
