Figure 12 illustrates a typical interface between the FT245BL and a MicroController (MCU). This examples uses two
IO Ports of the MCU, one port (8 bits) to transfer data and the other port (4 / 5 bits) to monitor the TXE# and RXF#
status bits and generate the RD# and WR strobes to the FT245BL as required. Optionally, SI / WU can be connected
to another IO pin if this function is required. If the SI / WU function is not required, tie this pin of the FT245BL to
VCCIO. If the MCU is handling power management functions, then PWREN# should also be connected to an IO pin of
the MCU.
The 8 data bits of Port 1 can be shared with other peripherals when the MCU is not accessing the FT245BL.
