Oscillator input.
Oscillator output.
Current reference – connect via a 12KΩ resistor @ 1% to GND.
USB Data Signal Minus.
USB Data Signal Plus.
IC test pin – for normal operation must be connected to GND.
Reset input (active low).
USB Power Save input. This is an EEPROM configurable option which
is set using a ‟Suspend on DBus7 Low‟ bit on FT_PROG . This option
is available when the FT232H is on a self powered mode and is used
to prevent forcing current down the USB lines when the host or hub
is powered off.
PWRSAV# = 1 : Normal Operation
PWRSAV# = 0 : FT232H forced into SUSPEND mode.
PWRSAV# can be connected to VBUS of the USB connector (via a
39KΩ resistor). When this input goes high, then it indicates to the
FT232H that it is connected to a host PC. When the host or hub is
powered down then the FT232H is held in SUSPEND mode.
