Table 1. Special Function Registers
I
FX1 supports the I
and SDA pins have open drain outputs and hysteresis inputs.
These signals must be pulled up to 3.3V, even if no I
connected.
Buses
All packages: 8 or 16-bit ‘FIFO’ bidirectional data bus, multi-
plexed on I/O ports B and D. 128 pin package: adds 16-bit output
only 8051 address bus, 8-bit bidirectional data bus.
USB Boot Methods
During the power up sequence, internal logic checks the I
for the connection of an EEPROM whose first byte is either 0xC0
or 0xC2. If found, it uses the VID/PID/DID values in the EEPROM
in place of the internally stored values (0xC0). Alternatively, it
boot-loads the EEPROM contents into an internal RAM (0xC2).
If no EEPROM is detected, FX1 enumerates using internally
stored descriptors. The default ID values for FX1 are
VID/PID/DID (0x04B4, 0x6473, 0xAxxx where xxx=Chip
revision).

ReNumeration™
Because the FX1’s configuration is soft, one chip can take on the
identities of multiple distinct USB devices.
When first plugged into the USB, the FX1 enumerates automat-
ically and downloads firmware and the USB descriptor tables
over the USB cable. Next, the FX1 enumerates again, this time
as a device defined by the downloaded information. This
patented two step process, called ReNumeration, happens
instantly when the device is plugged in, with no indication that
the initial download step has occurred.
Two control bits in the USBCS (USB Control and Status) register
control the ReNumeration process: DISCON and RENUM. To
simulate a USB disconnect, the firmware sets DISCON to 1. To
reconnect, the firmware clears DISCON to 0.
Before reconnecting, the firmware sets or clears the RENUM bit
to indicate if the firmware or the Default USB Device handles
device requests over endpoint zero:

Bus-powered Applications
The FX1 fully supports bus powered designs by enumerating
with less than 100 mA as required by the USB specification.
Interrupt System
INT2 Interrupt Request and Enable Registers
FX1 implements an autovector feature for INT2 and INT4. There
are 27 INT2 (USB) vectors, and 14 INT4 (FIFO/GPIF) vectors.
See
details.
RENUM = 0, the Default USB Device handles device requests
RENUM = 1, the firmware handles device requests
