4.9.2
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 oscil-
lator restarts, after the PLL stabilizes, and then the 8051
receives a wakeup interrupt. This applies whether or not FX1
is connected to the USB.
The FX1 exits the power-down (USB suspend) state using one
of the following methods:
USB bus activity (if D+/D– lines are left floating, noise on
these lines may indicate activity to the FX1 and initiate a
wakeup).
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. Note that
WAKEUP is by default active LOW.

Program/Data RAM
4.10.1
The FX1 has 16 KBytes of internal program/data RAM, where
PSEN#/RD# signals are internally ORed to allow the 8051 to
access it as both program and data memory. No USB control
registers appear in this space.
Two memory maps are shown in the following diagrams:

4.10.2
This mode implements the internal 16-KByte block of RAM
(starting at 0) as combined code and data memory. When
external RAM or ROM is added, the external read and write
strobes are suppressed for memory spaces that exist inside
the chip. This allows the user to connect a 64-KByte memory
without requiring address decodes to keep clear of internal
memory spaces.

The bottom 16 KBytes of program memory is external, and
therefore the bottom 16 KBytes of internal RAM is accessible
only as data memory.
