**Note 2 : 232 UART, 245 FIFO, CPU FIFO Interface, and Fast Opto-Isolated modes are enabled in the external

EEPROM. Enhanced Asynchronous and Synchronous Bit-Bang modes, MPSSE, and MCU Host Bus Emulation

modes are enabled using the driver command set bit mode. See Section 5.2 for details.

**Note 3 : Channel A can be configured in another IO mode if channel B is in Fast Opto-Isolated Serial Mode. If both

Channel A and Channel B are in Fast Opto-Isolated Serial Mode all of the IO will be on Channel B.

**Note 4 : MPSSE is Channel A only.

**Note 5 : MCU Host Bus Emulation requires both Channels.

**Note 6 : The Bit-Bang Mode (synchronous and asynchronous) WR# and RD# strobes are on these pins when the

main Channel mode is 245 FIFO, CPU FIFO interface, or Fast Opto-Isolated Serial Modes.

**Note 7 : The Bit-Bang Mode (synchronous and asynchronous) WR# and RD# strobes are on these pins when the

main Channel mode is 232 UART Mode.

**Note 8 : SI/WU is not available in these modes.

**Note 9 : The Bit-Bang Mode (synchronous and asynchronous) WR# and RD# strobes are on these pins when the

main Channel mode is 245 FIFO, CPU FIFO interface. Bit-Bang mode is not available on Channel B when Fast Opto-

Isolated Serial Mode is enabled.
