Split bus mode (BUS_CONF = LOW): 8-bit multiplexed address and data bus, and
separate 8-bit and 16-bit DMA bus
Generic processor mode (BUS_CONF = HIGH): separate 8-bit address and 16-bit
data bus.
Details of the bus configurations for each mode are given in
Table 3
. Typical interface
circuits for each mode are given in
Section 14
.

X: don’t care.
Dead: the USB cable is plugged-out and V
CC(I/O)
is not available.
Plug-out: the USB cable is not present but V
CC(I/O)
is available.
Plug-in: the USB cable is being plugged-in and V
CC(I/O)
is available.
8.12 Interrupt
8.12.1
Interrupt output pin
The Interrupt Configuration register of the ISP1583 controls the behavior of the INT
output pin. The polarity and signaling mode of the INT pin can be programmed by
setting bits INTPOL and INTLVL of the Interrupt Configuration register (R/W: 10h);
see
Table 25
. Bit GLINTENA of the Mode register (R/W: OCh) is used to enable
