PIC24FJ256DA210 FAMILY
18.1.2
18.1.2.1
PIC24FJ256DA210 family devices have a built-in
15 k pull-down resistor on the D+ and D- lines. These
are used in tandem to signal to the bus that the micro-
controller is operating in Host mode. They are engaged
by setting the HOSTEN bit (U1CON<3>). If the OTGEN
bit (U1OTGCON<2>) is set, then these pull-downs are
enabled by setting the DPPULDWN and DMPULDWN
bits (U1OTGCON<5:4>).
18.1.2.2
In Host mode, as well as Host mode in On-The-Go
operation, the USB 2.0 Specification requires that the
host application should supply power on V

the microcontroller is running below V
able to source sufficient current, a separate power
supply must be provided.
When the application is always operating in Host mode,
a simple circuit can be used to supply V
late current on the bus (Figure 18-6). For OTG opera-
tion, it is necessary to be able to turn V
needed, as the microcontroller switches between
Device and Host modes. A typical example using an
external charge pump is shown in Figure 18-7.
