supply voltage (3.3 V); it is recommended to connect a decoupling
capacitor of 0.01 µF

I
digital ground
DACK1
DMA acknowledge input; indicates that a request for DMA transfer
from the HC has been granted by the DMA controller; the active level
(HIGH or LOW) of the acknowledge signal is programmed by using the
HcHardwareConfiguration register (20H/A0H); when not in use, this
pin must be connected to VCC through a 10 kΩ resistor
input with hysteresis
DACK2

30
K8
J9
I
DMA acknowledge input; indicates that a request for DMA transfer
from the DC has been granted by the DMA controller; the active level
(HIGH or LOW) of the acknowledge signal is programmed by using the
DcHardwareConfiguration register (BAH/BBH); when not in use, this
pin must be connected to VCC through a 10 kΩ resistor
input with hysteresis
INT1
O
interrupt request from the HC; provides a mechanism for the HC to
interrupt the microprocessor; see HcHardwareConfiguration register
(20H/A0H) Section 15.4.1 for details
If the OneINT bit of the HcHardwareConfiguration register is set to
logic 1, both the HC and DC interrupt request will be routed to INT1.

O
interrupt request from the DC; provides a mechanism for the DC to
interrupt the microprocessor; see DcHardwareConfiguration register
(BAH/BBH) Section 16.1.4 for details

I
reset input
input with hysteresis and internal pull-up resistor
H_SUSPEND/ 33
H_WAKEUP
I/O
I/O pin (open-drain); goes HIGH when the HC is in the ‘suspend’
mode; a LOW pulse must be applied to this pin to wake up the HC;
connect a 100 kΩ resistor to VCC
bidirectional, push-pull input, three-state open-drain output
D_SUSPEND/ 34
D_WAKEUP
H9
I/O
O
I/O pin (open-drain); goes HIGH when the DC is in the ‘suspend’
mode; a LOW pulse must be applied to this pin to wake up the DC;
connect a 100 kΩ resistor to VCC
bidirectional, push-pull input, three-state open-drain output
H_PSW1
35
H10
connects to the external PMOS switch; required when the external
charge pump or external VBUS is used for providing VBUS to the
downstream port
LOW — switches ON the PMOS providing VBUS to the downstream
port
HIGH — switches OFF the PMOS
when not in use, leave this pin open
open-drain output
