Table 3.6.6 Pin Definition by Chip Mode (Channel B)
**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 3.3 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.
