Single-chip USB OTG Controller
15.1.5 DcInterruptEnable register (R/W: C3h/C2h)
This command is used to individually enable or disable interrupts from all endpoints, as
well as interrupts caused by events on the USB bus (SOF, EOT, suspend, resume, reset).
A bus reset will not change any of the programmed bit values.

EXTPUL
Logic 1 indicates that an external 1.5 k
pull-up resistor is used on
pin OTG_DP1 (in device mode) and that SoftConnect is not used. Bus
reset value: unchanged.
13
NOLAZY
Logic 1 disables output on pin CLKOUT of the LazyClock frequency
(115 kHz
± 50 %) during the suspend state. Logic 0 causes pin CLKOUT
to switch to LazyClock output after approximately 2 ms delay, following the
setting of bit GOSUSP of the DcMode register. Bus reset value:
unchanged.
12
CLKRUN
Logic 1 indicates that 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 suspend current requirements. The clock is stopped after a
delay of approximately 2 ms, following the setting of bit GOSUSP of the
DcMode register. Bus reset value: unchanged.
11 to 8
CKDIV[3:0]
This eld species clock division factor N, which controls the clock
frequency on output CLKOUT pin. The output frequency in MHz is given
by
. The clock frequency range is 3 MHz to 48 MHz (N = 0 to
15), with a reset value of 12 MHz (N = 3). The hardware design
guarantees no glitches during frequency change. Bus reset value:
unchanged.
7
DAKOLY
Logic 1 selects DACK-only DMA mode. Logic 0 selects 8237 compatible
DMA mode. Bus reset value: unchanged.
6
DRQPOL
Selects the DREQ2 pin signal polarity (0 = active LOW; 1 = active HIGH).
Bus reset value: unchanged.
5
DAKPOL
Selects the DACK2 pin signal polarity (0 = active LOW; 1 = active HIGH).
Bus reset value: unchanged.

WKUPCS
Logic 1 enables remote wake-up using a LOW level on input CS. Bus reset
value: unchanged.

1
INTLVL
Selects interrupt signaling mode on output (0 = level; 1 = pulsed). In
pulsed mode, an interrupt produces 166 ns pulse. Bus reset value:
unchanged.
0
INTPOL
Selects the INT2 signal polarity (0 = active LOW; 1 = active HIGH). Bus
reset value: unchanged.
