pin
crystal is used
required only for
applications driving a
square wave into the XTAL1
pin that has a DC offset
recommended for all OTG
applications
Remark: The link controls CHIP_SELECT_N of the ISP1507 so that other ICs can utilize
the interface pins when the ISP1507 is not selected.

maximum value is determined by the voltage
drop on PSW_N caused by leakage into
PSW_N and the external supply control pin

STPS0520Z; Schottky rectifier
Remark: Adding Schottky diode will bring
down the V
depending on the load current. However, it is
still within the requirement of Universal Serial
Bus Specification Rev. 2.0.
