Description
supply voltage (3.3 V); it is recommended to connect a decoupling
capacitor of 0.01
µF
digital ground
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 V
CC
through a 10 kΩ resistor
input with hysteresis
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 V
CC

input with hysteresis
interrupt request from the HC; provides a mechanism for the HC to
interrupt the microprocessor; see HcHardwareConfiguration register
(20H/A0H)
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.

push-pull output
reset input
input with hysteresis and internal pull-up resistor
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 V
CC
bidirectional, push-pull input, three-state open-drain output
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 V

bidirectional, push-pull input, three-state open-drain output
connects to the external PMOS switch; required when the external
charge pump or external V
BUS
is used for providing V

to the
downstream port
LOW —
switches ON the PMOS providing V

to the downstream
port
HIGH —
switches OFF the PMOS
