4.3
FX1 supports the I
2
C bus as a master only at 100/400 KHz.
SCL and SDA pins have open-drain outputs and hysteresis
inputs. These signals must be pulled up to 3.3V, even if no I
2
C
device is connected.
I
2
C Bus
4.4
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.
Buses
4.5
During the power-up sequence, internal logic checks the I
2
C
port 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),
or it boot-loads the EEPROM contents into 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).

USB Boot Methods
4.6
Because the FX1’s configuration is soft, one chip can take on
the identities of multiple distinct USB devices.
When first plugged into USB, the FX1 enumerates automati-
cally and downloads firmware and 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 hint 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 whether the firmware or the Default USB Device
will handle device requests over endpoint zero: if RENUM = 0,
the Default USB Device will handle device requests; if RENUM
= 1, the firmware will.
ReNumeration
4.7
The FX1 fully supports bus-powered designs by enumerating
with less than 100 mA as required by the USB specification.
Bus-powered Applications
4.8
Interrupt System
4.8.1
FX1 implements an autovector feature for INT2 and INT4.
There are 27 INT2 (USB) vectors, and 14 INT4 (FIFO/GPIF)
vectors. See EZ-USB Technical Reference Manual (TRM) for
more details.
INT2 Interrupt Request and Enable Registers
Note:
2.
The I
2
C bus SCL and SDA pins must be pulled up, even if an EEPROM is not connected. Otherwise this detection method does not work properly.
