PIC24FJ256GB110 FAMILY
18.1.2
18.1.2.1
PIC24FJ256GB110 family devices have 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 microcon-
troller is operating in Host mode. They are engaged 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 supply power on V

microcontroller is running below V
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
regulate current on the bus (Figure 18-6). For OTG
operation, it is necessary to be able to turn V
off as needed, as the microcontroller switches between
Device and Host modes. A typical example using an
external charge pump is shown in Figure 18-7.
