Interrupt Enable register (R/W: C3H/C2H)
This command individually enables or disables interrupts from all endpoints, as well
as interrupts caused by events on the USB bus (SOF, SOF lost, EOT, suspend,
resume, reset). A bus reset will not change any of the programmed bit values.
The command accesses the Interrupt Enable register that consists of 4 bytes. The bit
allocation is given in
Table 22
.

Description

EXTPUL
Logic 1 indicates that an external 1.5 k
pull-up resistor is used
on pin DP and that SoftConnect is not used. Bus reset value:
unchanged.
-
reserved
CLKRUN
Logic 1 indicates that the internal clocks are always running,
even during the suspend state. Logic 0 switches off the internal
oscillator and PLL, when they are not needed. During the
suspend state, this bit must be made logic 0 to meet the suspend
current requirements. The clock is stopped after a delay of
approximately 2 ms, following the setting of bit GOSUSP in the
Mode register. Bus reset value: unchanged.
-
reserved
DAKOLY
Logic 1 selects the DACK-only DMA mode. Logic 0 selects the
8237 compatible DMA mode. Bus reset value: unchanged.
DRQPOL
Selects DREQ signal polarity (0 = active LOW, 1 = active HIGH).
Bus reset value: unchanged.
DAKPOL
Selects DACK signal polarity (0 = active LOW, 1 = active HIGH).
Bus reset value: unchanged.
reserved
This bit should be always written as logic 0.
WKUPCS
Logic 1 enables remote wake-up through a LOW level on input
CS_N (For wake-up on CS_N to work, V
BUS
must be present).
Bus reset value: unchanged.
-
reserved
INTLVL
Selects the interrupt signaling mode on output INT (0 = level,
1 = pulsed). In the pulsed mode, an interrupt produces 166 ns
pulse. For details, see
Section 12
. Bus reset value: unchanged.
reserved
This bit should be always written as logic 0.
