DP pull-down:
0 — Disable
1 — Enable
0 — The pull-up resistor is disconnected from the DP line. The data
line pulsing is stopped.
1 — An internal 1.5 k pull-up resistor is present on the DP line.
The data line pulsing is started.
Remark: When port 1 is in peripheral mode or it plays the role of a
peripheral while the OTG functionality is enabled, it depends on the
setting of DP_PULLUP and the V
DP line to HIGH through a pull-up resister. V
When 5 V is present on the V
