PRELIMINARY

3.5
During the power-up sequence, internal logic checks the I
2
C compatible 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, FX2 enumerates using internally
stored descriptors. The default ID values for FX2 are VID/PID/DID (0x04B4, 0x8613, 0x0000).
NOTE: The I
2
C compatible bus SCL and SDA pins must be pulled up, even if an EEPROM is not connected. Otherwise this
detection method does not work properly.
USB Boot Methods

Interrupt System
3.6.1
FX2 implements an autovector feature for INT2 and INT4. There are 27 INT2 (USB) vectors, and 14 INT4 (FIFO/GPIF) vectors.
See FX2 TRM for more details.

Reset and Wakeup
3.7.1
An input pin (RESET#) resets the chip. This pin has hysteresis and is active LOW. The internal PLL stabilizes approximately 200
μ
s after V
CC
has reached 3.3 volts. Typically, an external RC network (R=100k, C=0.1
μ
F) is used to provide the RESET# signal.
Reset Pin
3.7.2
The 8051 puts itself and the rest of the chip into a power-down mode by setting PCON.0=1. This stops the oscillator and PLL.
When WAKEUP is asserted by external logic, the oscillator restarts and after the PLL stabilizes, and the 8051 receives a wakeup
interrupt. This applies whether or not FX2 is connected to the USB.
The FX2 exits the power down (USB suspend) state using one of the following methods:
USB bus signals resume
External logic asserts the WAKEUP pin
External logic asserts the PA3/WU2 pin
The second wakeup pin, WU2, can also be configured as a general purpose I/O pin. This allows a simple external R-C network
to be used as a periodic wakeup source.
