UM232H Single Channel USB Hi-Speed FT232H Development Module Error!
Unknown document property name.
Datasheet Version 1.3
Clearance No.: FTDI# 198
Optionally, RI# can be connected to another I/O pin on the MCU and could be used to wake up the USB
host controller from suspend mode. If the MCU is handling power management functions, then an ACBUS
pin can be configured as PWREN# and should be connected to an I/O pin of the MCU.
An alternative to connecting the pull-up network to the Reset pin, to prevent current from flowing back the
USB power bus line, is to connect the network ACBUS7 pin to achieve the same results but with additional
benefits. A function called PWRSAV# is used to prevent current from flowing the USB line in the same way as
connecting the reset to the a pull-up network. However, the PWRSAV# function has the additional feature
of being able to put FT232H into sleep mode when the USB host is powered down. There is one trade of o
using reset instead of PWRSAV#, in MPSSE mode the ACBUS7 pin can be selected as a GPIO pin, using this
pin from both PWRSAV# and GPIO mode can cause a conflict. PWRSAV# is enabled and disabled using the
EEPROM, this function is disabled by default. Figure 7.4 illustrates an alternative USB Self-Power
configuration.
