PIN INFORMATION
IRQ10
Interrupt Request 10:
In IRQ mode this out-
put indicates an interrupt request from one of
the cards.
When the CL-PD6722 is in DMA mode (see
Misc Control 2
, bit 6), IRQ10 is the DREQ to
be connected to DREQ0, 1, 2, 3, 5, 6, 7 of the
ISA bus. In DMA mode this signal is active-
high.

IRQ12/
LED_OUT*
Interrupt Request 12 / LED Output
: In default
IRQ mode this output indicates an interrupt
request from one of the cards, and is con-
nected to the ISA bus IRQ12 signal. When the
Drive LED Enable bit (see page
61
) is set, this
output becomes an open-drain driver for a
disk-active LED (see
ATA Control
register bit
1) or PC Card activity LED (see
Extension
Control 1
register bit 2).

IRQ15/
RI_OUT*
Interrupt Request 15 / Ring Indicate Output
:
In IRQ mode this output indicates an interrupt
request from one of the cards. When the
IRQ15/RI_OUT* Is RI Out bit (see page
62
) is
set to ‘1’, this output is the -RI signal from the
corresponding PC Card.

-INTR
Interrupt
: This output indicates a management
interrupt. This should be connected to the sys-
tem processor’s SMI or NMI interrupt input,
depending on the type of processor used.

ZWS*
Zero Wait State
: This output is connected to
the ISA ZWS (0WS) signal. It is driven low by
the CL-PD67XX when it is able to complete the
current memory access cycle in zero wait
states.
